As advertised - 4/25/2017
Reviewer: Eric Graves
Bought two of these to replace old ones. Design seems great and actually fit using the same anchors and screws from other brand I was replacing. Glad our dog won't have to hear low battery warning any longer!

Everything perfect - 4/24/2017
Reviewer: Cristina Romero-Hodson
We changed all the smoke alarms in our condo and decided to get exactly the same we had. Customer service was great in helping me find out which model was the one we needed. We installed them with no problem and with that ease we got just what we needed.

Smoke Detector - 4/24/2017
Reviewer: Rochelle Jackson
The package arrived in one box without any physical damage. All 10 units worked properly without any issues. My home is 10 years old and the smoke detectors fit and looked perfect.

I ordered 5 of these smoke alarms to replace the 10-year-old models in my home one started malfunctioning and I decided to replace all of them. I am not experienced enough to install new electrical wiring. Online research showed this is the replacement model for the old fire alarms. This model allowed me to use the same mounting bracket and quick connector wire for the electrical hookup. The quick connector was a little difficult to remove but after the first installation, I'm a pro! Ordering was easy, the product is reasonably priced,and it arrived quickly. I plan to order my next replacements in 10 years when these need replacement. AWESOME.
