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.
