I am very happy with the onelink smoke detectors. They are easy to program and I like the feature where all will sound when one detects smoke.

Reviewer: Basil Jones
I easily found the information I needed to make my purchase decision for replacing my old detectors and expanding with additional detectors. I didnt realize they needed to be replaced after 10 years and I bet most people dont. If one of my original wired detectors hadnt failed, I probably still wouldnt know. Ordering was easy and I received the detectors I ordered in just a couple of days. My only complaint is that the detectors are a bit pricey. They were very easy to install and set up.

This product is awesome. All I had to do was run one circuit for this smoke and get battery smokes for the rest of the house. Fast, easy, and worth the money.

Reviewer: Art Kibby
We had 3 previous hardwired alarms, so we replaced them with these. They dont seem to communicate with any of the battery powered ones or with each other, even though we set them up per the instructions
