Rated 4.5 out of 5 by 85 reviewers.
Rated 5.0 out of 5.0 by install it and your done for 10 yrs as an apartment manager, it is essential that smoke detectors always work. tenants do not always replace the battery. that's where this product comes in and solves multiple problems. with a 10 year battery life, self-contained it never needs service. fire inspectors passed this product at installs in minutes and activates at once and completes a self-test and your done. I have 25 of these installed and have never had any problems or issues...I would recommend this product to everyone. dave June 4, 2013

Rated 4.0 out of 5.0 by This product is easy to install and can be safe for up to 10 years. This device will save on changing batteries for up to 10 years. Now we will not have to worry if we forgot about the time of year. May 13, 2014
Rated 1.0 out of 5.0 by This product is Junk I bought this 6 months ago. Last night it started to alarm. There was no smoke or fire. It continues to smoke. I was hoping to get a product I didn't have to worry about for 10 years or so. Instead I wasted 20 bucks on an alarm that lasted less than 6 months. Never again. Made in China. Don't buy this product. July 21, 2014
Rated 5.0 out of 5.0 by Full-filled our needs Mounting of the smoke detector was easy and will provide many years of peace and confidence that we will be protected. May 19, 2015
Rated 4.0 out of 5.0 by O.K. Smoke Alarm This is an OK smoke alarm. Pro - lasts 10 years (hopefully) Cons - If you detach the smoke alarm from its wall mount holder it will be deactivated and CAN NOT be re-activated. It is meant to be a permanently mounted device for 10 years. Once the battery runs out the whole device must be discarded. March 24, 2015
Rated 5.0 out of 5.0 by Great Safety Device Installation was very simple and I'm relieved by not having to replace a battery every 6 mos. April 21, 2015
