I think Sentry Security bought out the company that existed when I bought the house, but they've been good. Everything was very simple and self-explanatory. I would say they're 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.
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.
