Easy Installation

The alarms in the house I purchased at the end 2018 had these alarms, and I noticed they were already three years out of date, and were still working. I decided to replace them with these from the same company, as they seem to be pretty reliable.

Replacing existing detector was a snap

This new detector was replacing an existing one, which was at its end of life. The installation was very easy and quick. I will definitely be purchasing any detectors I need from USI in the future.

Does Not Fit Well

We purchased this model MCN108 because we were told it was the correct replacement for an older model CD-9385. However, even with changing to the new universal bracket, we found that the alarm does not fit as snugly against the ceiling as the old model did.

Wonderful replacement

We built a new home and the builder installed Universal products. After 7 years both stopped working so I got on Amazon and ordered two replacements. Not long after, one stopped working and when I checked the manufacturing date, it was 5 years old already. Order direct from Universal and avoid additional costs!
