Great price! Great Service! February 7, 2015
Reviewer: Joe Francis from Reston, VA United States  
After 11 years in our house, I decided to replace all of the smoke detectors. After much research I settled on the FA 3120B. SmokeAlert had the best price, even beating Amazon. The detectors were shipped promptly and arrived in a well packed box. All of them worked properly and now I'm set for another 10 years. Thanks SmokeAlert!

I placed my order with ease and it arrived within days. All the detectors had recent manufacture dates. I would definitely recommend Smoke Alert to others.

Superior Service January 27, 2015
Reviewer: John Polacek from Lake Barrington, IL United States  
As we have just installed our new smoke detectors, I am unable to comment upon their performance. I would, however, like to state that our order experience with Smoke Alert was great. Not only did Smoke Alert offer us the best price, but delivery of our smoke detectors was prompt. We will definitely order from Smoke Alert in the future.

Excellent service January 27, 2015
Reviewer: Anonymous Person from West Des Moines, IA United States  
This was a replacement for the BRK 86RAC smoke alarms.  Installation was simple and easy. We knew the BRK 86RAC alarms were going because they would randomly chirp or go off. We have not had that issue with these units yet. We had a problem with the battery door on one of the units and support was excellent. We were sent a replacement  right away. Chris was very helpful with everything. I would definitely shop again on this site.
