CUSTOMER REVIEWS

Rated 4.4 out of 5 by 17 reviewers.
Rated 5 out of 5 by Nice! A no frills smoke alarm that installs in just a couple of minutes and has a great price. I got this for our camper and it's perfect. A little smaller than the old one and it comes with a battery as well. Awesome value. June 28, 2014
Rated 5 out of 5 by It could save your life! I purchased these on an impulse buy. I was walking down the water heater isle and saw these at such a great price. I figure I should pick up a few and install them throughout the house. I install them that weekend and forget about them. A few months later, I'm in my bedroom and I hear a loud beeping coming from downstairs. I go to investigate and find my living room full of smoke. The smoke was caused by frayed wires on a home entertainment system. If it wasn't for this alarm, the smoke would go unnoticed leading to an actual fire. At this price, I would say to buy one for your friends and relatives as well. There aren't many gifts that you can give that can save someones life. April 10, 2013
Rated 4 out of 5 by Size doesn't matter. The description clearly states "compact design". It works just as well (maybe better) as larger units but requires less space to install. It's a smoke detector, not a manhole cover. I have several of these in my home and have no complaints. They are easy to install and maintain. Battery life has been satisfactory. No surprises.

Rated 4 out of 5 by Great size, nice product, batteries were bad The smoke detector was small (which is great) and functional - plus inexpensive. They come with batteries. I bought four - from two different Home Depots - one set was perfect, the other, the batteries were bad, to the point that the one set were leaking. October 7, 2014
Rated 5 out of 5 by Excellent value I have installed more than 10 of these in several locations and they have been in service for over a year now. These run on single 9V battery which is included with the package. These are UL listed so meet the required standards. I really don't see the point in buying the more expensive ones unless you need dual power supply i.e. the 120V and 9V. July 16, 2012
