Sentry Security is awesome. My experience with them was beyond positive. They are very friendly. They educated me and totally walked me through everything. They are hands-on, pleasant, lovely people. I would give them an A+.
I bought a town house with an older alarm system, so they upgraded it, and they monitor it. I thought the installer was great. He was a nice guy, and he did a good job. I'd say they deserve an A.
I got a new system from Sentry Security. I've used them for a long time, and I like just about everything about them. They respond quickly and have a good product. They're an A.
They were on time and set up everything. It was great. I'd give them an excellent rating.
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.
Hiring Sentry was a positive experience. They were nice. I've been using them for six months. I would tell other homeowners that they should use them—A.
They're been very responsive. I've used them for maybe three or four years. The people involved have been very good and very professional. I would recommend them. They get an A.
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.
