Product as described super fast shipping. Replace old First Alert sensors - new connectors were very easy to install. Would buy again.

Excellent service

Product delivered on time and was exactly as described on the site. I purchased these to replace previously installed detectors that had reached their life span. Included instructions easy to follow.

I started a new propane stove after installing these smoke detectors and the stove initially was very smoky and the detectors worked well

Easy replacement

Replacement for original installation. Used same make/model as original which allowed direct plug-in to wired system. No problems.

Easy Install

Needed to replace six BRK units. Wanted both ionization and photoelectric sensors in a hardwired detector with battery backup. First Alert offered the desired features in a six-pack at a reasonable price. My son installed them. The new base plate was bigger, but the screw holes were the same. In fact, it wasn't necessary to remove the screws, just loosen them. Another plus was the wiring harness was compatible with the existing electrical source. It just plugged right into the back of the new unit. Except for climbing the ladder, this grandmother could have done the installation. The units have been in place about two weeks and so far no false alarms.
