5 of 5 Best Smoke Detector/Alarm for the Bucks March 16, 2020
Reviewer: Donald Walker from LAS CRUCES, NM United States  
This is the best smoke detector/alarm for the price, and SmokeAlert is the best place to buy it.  Recent studies have shown photoelectric detectors are significantly better detectors than ionization ones at providing early warning for both smoldering and raging fires (ionization may detect raging fires up to 90 seconds sooner, but terrible at detecting smoldering fires).  It has been recommended that ionizing detectors be replaced by these type of detectors. I agree. That is why I have replaced all the detectors in my home.

5 of 5 Great Service February 6, 2020
Reviewer: John from Columbia, SC United States  
This company is one of the most efficient organizations I have done business with.
They also stock some hard to find units that you wont find in a big box store. Price is good too.

5 of 5 Trustworthy Company September 23, 2019
Reviewer: Robert Lavisky from CLARKSTON, MI United States  
This product is sold by a company that is owned and operated by professional  firemen, so they must know which is the best smoke alarm to have in your home.   They're cheaper than Amazon & Lowes also.
