  • " 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 experience. "
  • " 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. "
