Review: Peace of Mind - So far so good. I’m glad I purchased these. I have peace of mind both upstairs and downstairs. I’m glad these came in a pack of two. These were a great price for combo Smoke/CO detectors. The units are not too big and blend into the wall nicely, even with our grey walls. The units are good quality and look good. I like the feature that I don’t have think about changing out batteries all the time. The batteries inside are meant to last 10 years. Moreover, the units blink regularly to show the power is working and I can manually test the units too. The alarms are very loud, so no one should sleep through them. I installed the alarms without any issues and they come with everything I need for installation. Instead of using the screws to mount the units, I used command strips because I did not want to put holes in my walls.
Review: Good quality, work well. - Received them in a timely manner. Worked as described. Batteries included are good quality, and installation was easy. Would definitely buy again.

### ⭐⭐⭐⭐⭐ Good Product as described, safety FIRST
*by V***R on January 9, 2026*

Purchased for a child care setting to work as a backup to our hard wired system. We replace the batteries every 6 months or so and have had no issues. They are sturdy and easy to install. When we test them they are loud enough without being so loud they disrupt other areas of the building. They are quiet otherwise! Like most, we will replace them in 7 years as recommended. The batteries might last longer but we replace them as an extra precaution. We have not tested them with actual smoke and fortunately have not had them go off.
