Very Happy

The Carbon Monoxide Detectors installed when my hose was built 11 years ago began to fail...replaced batteries, but began beeping always at night it seemed after a month or two. Since I replaced them with new units, I have had no problems whatsoever. Very Happy with purchase. Have recommend this to many other residents of my development.

wired and battery alarms

In my house, I have both wired and battery alarms installed, but 15 years of trouble-free operation is enough for them, so I figured it was the right time for a replacement. The hardwired veteran was replaced with the BRK C0512BN, 'cause I was looking for an inexpensive, easy to mount and snap to use model. Honestly, neither I've looked through manuals nor specifications - the 5 star rating bribed me. Additionally, I was glad to discover a battery backup (handy in case of electricity issues). Even though I've spent some 10 minutes on User Guide studying, I enjoyed smooth and quick installation - the feature I was looking to pick up initially.
