Does Not Fit Well

Reviewed: 02/06/2018 by Charlene Mason

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.

Our old alarms were 8 years old when they went out. I called customer service and spoke to Michelle M. What a great CS person she called me back and sent an email with the replacement number. When I received it, what a perfect fit. Thanks Michelle M

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!

I can not find these in any local store and so I am glad I have found a store I can rely on to replace my carbon monoxide detectors. A quick fix and lasts a long time.

This item was installed with great ease due to the compatible nature of the product. The CO detector is more current compared to the old, expired version obtained 7.5 years ago. We also ordered the smoke detectors and look forward to ensuring the safety of our family. Shipment was in a timely fashion.
