Faulty out of the box

Would Not Recommend

Installed the unit and it was defective out of the box .For a device that we are entrusting our safety with, the quality is very low. How could you ever trust this to work in a emergency event. There should be some type of regulatory body overseeing this.

Perfect Replacement/Upgrade

Would Recommend

We had a mix of First Alert and Kidde, and the Smoke/CO models had come to the end of the 10 year life, plus we wanted to try the 10 built-in battery models.

And for the CO and Kidde replacements, we just loosened two screws, put the new mount on, and attached the Kidde to First Alert wiring adapter that was included. Two Smoke/CO and seve...
