“They were very professional, on time, and did a really nice job installing. I’d give them an A+ overall. I’ve recommended them.”

“I’d give them an A+. It was just what we expected.”

“They put the whole security system in my house. I think they spent some time understanding what was needed and then came up with a solution for that, rather than just pushing the standard stuff. That was something I appreciated over the other companies I talked to during the same time. They sent a technical rep who took the time to look at everything in the house and come up with a few proposals. It was detailed and customer friendly. He was not trying to push everything. He said,

‘This is not needed. That is not needed. This should be what you need.’ I was able to compare it. There were two other companies who came, and their technical reps were trying to sell me a fully outfitted Cadillac, which was not necessary. I would
give them an A for the overall experience.”

“I haven’t had any issues. I don’t really communicate with them often, but they’ve been responsive when I’ve needed to talk to them. I’d give them an A for the overall experience.”

“I’ve been with Sentry Security for years, and they’ve done work for my business also. They’re responsive—when you call, you get somebody. Either they are right there to speak to you at that moment, or they get back to you as soon as they get
back into the office. I chose them because they bought out the company that I was with before. I’d rate them as an A.”

“I like Sentry Security. The previous owners had used them, so we just continued using them. I’d give them an A grade—I had no complaints.”

“I like that when you call them on the phone, they answer. They’re good at troubleshooting. The installation went well, and the billing’s easy. Everything makes it seem like they’re a good company. We chose them because they were the most
receptive, so we had the most confidence in them. Sentry Security gets an A.”

“We use Sentry Security, and they do very good job. I’d give them an A rating.”

“I’ve had Sentry Security for years, and I’ve never had a problem. They get an A.”

“I had a security system installed a while ago, and Sentry Security came in and made it wireless. I like the way the system operates. I can turn it on and off from my phone now, which makes it nice. It’s all good. Their grade would be an A.”

“I’ve used Sentry Security for about four years. The complex I used to live in hired them. I liked them, so I wanted to use them again.”

“When I bought the house, Sentry Security was the company that the previous owner had used, so I just continued the service. The employees were very good. I would give them an A.”

“The security system was already installed in the house when we bought it, and I haven’t had to call them for any other issues.”

“They monitor an existing system, but they did the original install before we bought the house. Starting the service was fairly painless and quick, and they have always been responsive. I haven’t had any issues. Sentry Security gets an A.”

“They were on time and set up everything. It was great. I’d give them an excellent rating.”

“We used Sentry Security at our former home where we lived for 34 years. When we moved, we called them to take over the system, and they attempted to do that. It was old technology, so they upgraded it as we went along. We did have one
additional problem after that, but they came out and took care of it. They have been very responsive, so I am a satisfied consumer.”

“We have been using them for about one year. The security system was already in the house that we bought, so we got the service from Sentry Security. When we moved in a little while back, they were very helpful in getting it all set up and
familiarizing us with the system. We’ve had a couple of accidental alarms go off—nothing major—but they followed up quickly, so we appreciated that. I would give them an A.”

“They were very nice, very friendly, and came out when they were supposed to. I’ve been using their services for four months. I chose them over another company because my husband just made some calls, and that was the best response that he had.
If another homeowner casually asked me about this company, I would tell them to give Sentry Security a call. I’d give them an A.”

“I haven’t had any problems. Everything works the way it’s supposed to. I’ve been using them for a little over a year, and there have not been any significant issues at all. They’re a fine company. They get an A- from me.”

“They were timely when I called them to make an appointment—they were able to get here within a few days. They aren’t one of the bigger companies, so I think they pay more attention to customer service. Everyone has been really great. I’ve been
using them for about a year. I chose them over another company because my parents use them. I have no complaints, and I would recommend them to anybody else. I feel like they deserve an A.”

“What they said they would do, they did. I thought they represented the stuff well. That’s the bottom line. I checked with a couple other services, and I decided we’d try Sentry. They get an A—I have no complaints.”

“When our door was locked, somebody tried to open the door. Sentry called immediately. I liked their promptness. I’d recommend them and give them an A.”

“I like that they answer my phone calls. I’ve been using them for about ten years. I’d grade them an A.”

“Sentry has good service and a good response—I’ve had no problems. I heard about this company from a friend of mine. The personnel and customer service are very nice. They follow through. I have no problems. I’d tell another homeowner to use
them. I’d give them an A.”

“I like the way the system works—I think it works pretty well. I think the people involved were very friendly and helpful. They’re pretty responsive, and they’re very good at answering questions. They get an A. I would recommend them.”

“They hooked up the system and did what they did—no frills. They were very professional and very courteous. They get an A.”

“They’ve been professional and polite, and I feel like I got what I’ve paid for. We initially had some issues in getting the security system up and running. The company was very responsive—they sent out another person who could get it going
again. Any questions I had, they were very good about answering them. They’re a pretty good company to work with. I’d give Sentry Security an A.”

“I’m satisfied by what they’ve done. There has never been an issue that I’m aware of. I’d give them an A.”

“They respond right away. I’ve been using Sentry for ten years. They’re fine right now. Their customer service and people are good. I’d recommend them. I would give them an A-.”

“Sentry Security is very good. Whenever you call them, there is always somebody in the office that you can talk to—not a machine. The gentleman that was here was very clean, very quick, and polite. Their customer service was excellent, and
they’re very helpful. I would grade them an A+.”

“I like Sentry Security’s customer service. They’re always easy to deal with. We used to be locked into a seven-year contract with another firm whose customer service was awful, so I was looking for a company that would listen to us and help us
fix our problems, and Sentry did. They definitely get an A.”

“We’ve been using Sentry Security for roughly two years, and we’ve never had any issues with them. It’s a very good service. There isn’t anything I wish they would do differently. I’d give them an A. We like them.”

“Everything has worked out well with Sentry Security. I like that they respond quickly to anything. The alarm went off before. I got a call instantly. And they also contacted everyone I have on my paperwork. My experience with them has been
good. They get an A+.”

“Everything is fine. They’ve just been very responsive. They were very good to me after a break-in. They got here very quickly. I’ve been using them for four months. My experience with them has been very positive. A is fine.”

“Sentry Security is great. They were very helpful with the installation. I actually haven’t needed to use them. They call me. Sometimes my housekeepers will accidentally set it off, and I always get a call. They’re like, ‘No problem,’ and they
take care of it. I’ve only had them since March, but they’ve been fine. I think the best thing about a security company is when you don’t have to think about it. My experience has absolutely been positive. They get an A.”

“Everything is great. Sentry Security has friendly customer service. They were prompt. They were communicative. Everything about them was good. It was a good experience. I’d give them an A rating.”

“I’ve had Sentry Security for a long time. I have no complaints about them. They were very reliable, I would say. They would be A. I cannot complain.”

“It’s great. It was a good experience. It was our friend who recommended them, and we’d had their services before. I would give them an A.”

“Everything is great with Sentry Security. I like the fact that I can remotely control the system from my cell phone. I’ve had absolutely no problems. My experience was good. I’d give them an A.”

“It went fine with Sentry Security. We had a great interaction with them. They installed the system in our house after we had a break-in. My experience has been good. They were responsive. I guess ease of use of the system is good. I think my
husband’s ability to control it online is good, too. And they have an app that obviously allows you to see when your alarm is disabled and stuff like that. I like just being able to be out of town and still see remotely what’s going on—I think
that’s very positive. My experience has been generally good. I’d give them an A.”

“Everything went just great with Sentry Security. They just did a really nice job. They were very thorough. We were very pleased with them. My experience has always been positive with Sentry. I think we’ve been using them for a year maybe. I’d
give them an A.”

“With Sentry Security, things are going fine. I talked to the gentleman who was out here to install everything. They were just very professional. Everything went really well. I never had to call them back. My experience was good. I would give
them an A+, because if I had a question I’d call them, and they’d help me.”

“Everything is fine. I haven’t had any issues, not that I’m aware of. Nothing really sticks out at me—the quieter the better. I bought the house in September, so I’ve been working with them since then. There haven’t been any issues at all. I’ll
tell you that in a heartbeat—I’d give them an A+.”

“Sentry Security is great. I mean there are a couple of things that I needed to call them about, just because when the person came out here to install it, he told me a couple of things like shortcuts on the keypad. As soon as he left, I couldn’t
remember what they were. It’s not something so pressing that I can’t live without it, and I just haven’t had a chance to get around to calling them to ask what those shortcuts were again. Other than that, I’m totally happy with it. My experience
has definitely been positive. They get an A+.”

“I have people overseeing that, but I haven’t seen Sentry Security’s work yet. I’m sure it was fine. I like them. They did work in the summer. Then they did a follow-up just recently. They did work in September. It was very good. I love them.
I’d give them an A.”

“Sentry Security is good. They have good service. I’ve actually had some issues with our alarm, but they’ve been very responsive in coming out and taking a look at it. Every time someone has come over, they’ve been very helpful and dedicated to
making sure that they’re solving the problem as best they can. They’re very friendly folks. It’s been a good experience. I’d give them an A.”

“I think Sentry Security is OK. I didn’t deal with them; my husband did. My husband says it’s very good. He would give them an A.”

“Everything was fine. I can’t think of anything bad about Sentry Security. Nothing wrong with them at all. It was a pretty good experience. I’d give them an A.”

“Everything went just fine. Sentry Security would get an A+.”

“It was OK. I don’t happen to live there anymore. Sentry Security is good. I’ll give them an A.”

“Sentry Security is great. I love their company. They’ve been very helpful with our security needs—a perfect ten across the board. They were really friendly too. We’ve had experiences with another security company before where you’re kind of
treated like a number. The guys at Sentry are very friendly and approachable. If you have a problem, they can fix it.”

“They are absolutely wonderful in every possible facet. It has been a totally wonderful experience with Sentry Security. I’d give them an A+.”

“We’re very satisfied with the system from Sentry Security. We left another security company because they just got too big too fast. I think customer service and availability are really a key thing with Sentry. The technician we had at our house
was wonderful. We’ve been happy, so they’d totally get an A.”

“They’ve done phenomenal work. They’re just awesome. I have no complaints whatsoever. The quality of their work, the overall representation, and their friendliness stand out—they’re absolutely awesome. We’ve had a lot of service people in our
house, and I would say they’re by far the best. We recommend them to everybody.”

“Sentry’s good. They came in and did a thorough job. They assessed the situation, and they made suggestions for improvements. They were professional, timely, and responsive. They did a good job. Overall, I would say it was a very positive

“Sentry has worked out really well. It’s so good. Everyone was really courteous and professional, and we’re pretty impressed.”

“I’d recommend them. They communicate well and show up on time. I’ve been with them for about 15 years. I’ve never had a problem. They’re very good, and as soon as the alarm goes off, they call us or they call the police or the fire department.
I really like them.”

“I’m pleased with them. If the alarm accidentally goes off, they’re real good about responding quickly. Sometimes I accidentally set it off, so I get a phone call and I give them my name and password. I’m getting good service from them.”

“Their service people have been fantastic every time they’ve come out. They somehow know just what the problems are, and they push all of the buttons to make our system work better than we can on our own. They’re able to keep us up-to-date and
functioning, so we think they’re great.”

“Right now, Sentry is doing great. I haven’t had any problems. Everything with the system has been great so far.”

“The service has been fine, and the people have been very helpful when I had to deal with a false alarm. The response time was great. Overall, it’s pretty positive. I’d give them an A grade.”

“I thought they did a very good job. I was happy with Sentry’s service. I thought their personnel also did a great job. I was very happy.”

“They’ve been excellent. When the service guy came over, he checked on the response time. I give them high marks. So far, we’re satisfied.”

“We really like them. Sentry gives us a constant, 24-hour service. When I first got it, I made a mistake with the alarm and left home. The police came, and their response time was good. The personnel are all great, too—there are no problems.”

“The service has been fine. I haven’t had the opportunity to test the response time, but they’ve been very nice. I’d probably give them an A grade.”

“They’ve done just fine. This is ongoing service. Basically they have it set up so I get an email saying that my alarm’s been triggered. It has been good customer service.”

“They’re okay. I still use them. They’re fine.”

“The service has been fine—no problems. It’s been on going for a while.”

“They’ve been great. Very helpful, very informative—they stayed in contact with me.”

“The service has been great. Everyone’s been very nice. I have no complaints whatsoever; everything seems to be working out. Our house has not been broken into yet.”

“We’ve only had it for about a month, so it’s hard to say much. It’s fine, so far. No complaints.”

“The service has been fine—no issues. The conversations, when I’ve had to call, have been good. They came and we had no issues.”

“Everything’s been fine. Both sets of personnel were good.”

“Their work has been done to my satisfaction.”

“I am satisfied, and everything is good. I have had no problems. I have used them since we moved in, for the last seven years. I would recommend them to other people.”

“Sentry Security is fine. They’re our security company.”

“They are very good. It’s so far, so good. I’ve been using them for three years, maybe more, but everything is good.”

“We have their system. I have a contract with them. Everything is OK.”

“So far, so good. When I’ve needed them, they contacted me promptly. There was no reason for them to show up, but the response has been good when we’ve set off the alarm. No complaints overall. I would recommend them.”

“It was excellent. We’ve never had any problems. I’d recommend them.”

“It was fine. The last time they were out was when they installed it, and they haven’t been out since then. They did an installation, and I was satisfied with it. I have already referred them to someone else.”

“Everything was fine. I’ve never had any issues with Sentry Security. Any time that I’ve needed them, they’ve shown up on times and were prompt. No problems. No complaints.”

“They provided my security system. The owner lives three houses down, so he was over a couple of months ago. The last time I had them out, they had to just fix a sensor. I’m satisfied with their work. I would refer them to somebody else.”

“I’m very happy with them. When they came and installed it, they were clean and showed up when they were supposed to. They were very professional, respectful, and on time. They have always been on time. I’d recommend them.”

“They did fine. I’m satisfied with the work they do.”

“Sentry does very well for me.”

“The work Sentry Security does for me was fine.”

“They did a good job for me. It was fine. I would recommend them to other people. I haven’t had any issues with my security system since they were here. None at all. We’re very happy with what they’ve done.”

“I guess they corrected it, whatever it was. I’ve been satisfied, and I haven’t had any issues since then.”

“I had a burglar alarm system, and they provided maintenance and monitoring. I would rate the work they did for me as very good.”

“Fortunately for me, I haven’t had to use them since they installed the system. I’ve just called them a couple of times when I had to change a number or something. It’s been satisfactory.”

“We like Sentry’s services. It’s been going very well.”

“I’ve been satisfied with the work. It’s been fine. I’ve used them for seven years. They do the security for my home.”

“I don’t have them anymore because we’ve moved, but I was very pleased with them. I was with them for a long time. If the alarm ever went off accidentally, they would always respond quickly.”

“I am very pleased with everything.”

“We’re pleased with Sentry.”

“I’m very happy with it. I haven’t had any problems. The two times I’ve screwed up and walked out the door without turning the alarm off, somebody calls me promptly. I haven’t done that lately, but you never know. When they installed it, they
came when they supposed to and communicated well. I think they installed it in ’01.”

“They’re fine.”

“The last time they were out at my house was a couple of years ago. I’ve had them for 20 years. The last time they were out, they replaced some batteries. I was satisfied with their service. Excellent company. I would refer them to somebody

“I’m happy with the service. I’ve had this service for years and years.”

“I thought they were fine. I have been happy with the work they did. I have not had any billing or scheduling problems with them.”

“Sentry Security has good service.”

“I’ve been pleased with Sentry’s service.”

“Sentry is very good. I would recommend them. Any time I’ve needed them, they’ve shown up promptly.”

“I like them. They’re really good. I think we’ve had the system for 10 or 15 years. They’re usually pretty good when they call or we call them.”

“Sentry Security did some work for us. We’ve had them for years. We upgraded to a new panel a couple years ago. They did an awesome job. Then we had some trouble. They came out and tracked it to our phone line. It wasn’t the system. Something
specific that I like about them is that you don’t have to wait too long for a service call. They come out the next day.”

“I’ve been using them for a while, since I built my house. It wasn’t always Sentry; it was something different before that. My alarm has never gone off, and we’ve never been broken into. I am satisfied with them.”

“Everything is fine. We don’t have any problems.”

“I have no problems with them. They’ve been good.”

“I have Sentry. I’m satisfied with the work they’ve done—we’ve had them for about 40 years.”

“I feel fine about their work. They do a great job. They have responded promptly. I have had no complaints.”

“I was very satisfied with Sentry Security’s work, and I’d refer them to other people. They were pretty thorough—they didn’t have to come out a lot of different times. They troubleshot the problem pretty well, and they were able to service it
pretty quickly.”

“I’m happy with the service. So far, so good. It’s been almost two years now since my present system was installed. I haven’t had any problems. I would recommend this company to other people.”

“I am satisfied with Sentry Security, very much so. I have been using them for 15 years, maybe longer than that. I certainly would recommend this company to other people.”

“The job they’ve done for me has been good. I don’t have any complaints. There haven’t been any billing issues or anything like that.”

“I like it OK. I’m continuing to use it. I would recommend them to someone else.”

“I’m satisfied with them. I’ve used the same service for the last 20 years, and they took over from the company that I had before. I’m satisfied with the service they’re giving me.”

“They installed my alarm system, and they monitor it. I think the work they do for me is excellent. I have no complaints. I’ve recommended them to other people.”

“They’re great. I’ve had no problems with them. They’ve handled any problems I’ve had. They’re really good.”

“They’re doing fine. I’ve been using them for maybe three or four years. I would recommend them to other people.”

“I think their service has been fine.”

“Great. I was very happy. No problems. Had them for 20 years.”

“They’ve been great. I think I’ve used them since I bought this house, so that’s been 10 or 11 years. I would recommend this company to others. I particularly like that if I have to change a battery or something, they tell me how to do it. They
don’t make me have someone come out. They save me a little money here and there—it’s just a battery.”

“Sentry Security is fine.”

“It was basically 13 years ago that we had the system put in, and Sentry Security has just been servicing it. They do a good job as far as that goes. I’ve had no trouble or anything. I’d recommend them to somebody else.”

“We’ve been clients of theirs for a while. It has changed owners, so we’re ongoing customers with them, and their service has been fine.”

“I like them pretty well. It seems to work okay. We haven’t had any problems. Things have gone off, and they have responded quickly. I have been with them for a while. I would recommend them.”

“I haven’t had any problems with them because we haven’t had to use the system at all. We got the alarm system, but we haven’t had any alarms go off because we haven’t had any problems. We’ve had them for quite a while now. No issues at all. I
don’t have anything negative to say about Sentry.”

“I have been using them for probably 15 to 17 years. I would recommend this company to other people.”

“The work they did was a new installation. I wasn’t here. It was a long time ago, like five years ago. They haven’t been out to my house for any kind of maintenance, so all I do is pay the bill. When they came out to my house initially, I was
satisfied with them. It was an installation, and that’s that. There were no problems or complaints. I would refer them to somebody else.”

“They’ve done a great job. I’m satisfied, and I’d definitely recommend them. No complaints whatsoever.”

“They’ve done a good job, and we haven’t had any problems. Any time we’ve accidently tripped the alarm, they have responded promptly. We don’t have any problems.”

“They installed our security system. They’re great.”

“In the last three to four years, they have been our security system, but I didn’t have any recent work done. We’ve had them for years, though. In general, they’re great. I’ve never had any billing issues or an actual alarm or anything like

“They did a fine job. They bought out the company that we used to have, but they do a fine job. I have no problems.”

“We’ve had them for a long time. We’ve been very pleased with them. They’re very prompt when we accidentally set the alarm off, and they’re very responsive. We’re very pleased.”
