I ordered two of these hard-wired smart alarms. They were shipped out the same day. Exactly what I needed to replace what was there. Only reservation is that the prior units' batteries did not last 10 years. Otherwise highly recommend.

So far so good...
It's good to have the original brand.

Good replacement for MICN109
I bought a couple of these to replace 2 MICN109 that reached their end of life. I wish they had MDSCN111 in stock, but so far the MIC1509S helps on certain areas of the house.

We use this product because that was what was in our house when we moved in. We have never had one last 10 years though.

Works as expected
Bought to replace an existing USI smoke and CO detector that had reached its ten year end of life. Only issue is that I had to use the new mounting bracket since the new unit was not compatible. However, the three-wire connector from the old one did fit into the connector for the new one. Has been in service for several weeks with no unexpected alarms. Would buy again.

Great product with 10 year battery!!! Easy to replace aged product 10 years old. A ladder and a screw driver was all that was needed. Better now! Thanks!

Easy to install in existing electrical box, good directions. I like that it includes CO detection and both photoelectric and ionization fire detectors. I have 3 of these alarms installed.

The original alarms were due to be replaced in our house and choose the same USI replacements. The mounting bracket had to be changed but overall the project was very easy and quick. Having the 10 year battery is great because we are away a lot and one time a neighbor called us to tell us our alarm was beeping. The battery had to be changed and we were out of town. This model gives us peace of mind when away.
