Rated 4.3 out of 5 by 8 reviewers.
Rated 4.0 out of 5.0 by Looks nice on the wall I have been watching this product for about a year and now it has reached a price point where I can afford it. Installation of the required 2-gang box was easy in my older house built on a slab because it does not have fire block. This unit looks good on the wall. From what I have heard CO alarms are most effective if mounted low, yet most look like they belong on the ceiling. I'm also looking forward to never hearing the low battery chirp. December 30, 2014
Rated 4.0 out of 5.0 by GREAT PRODUCT, WHEN HARDWIRED IS REQUIRED. Good looking, solid hardware. Basicly a hardware version of the high end plug in or battery operated unit. Only complaint, the led display is very bright ( this may be adjustable, havnt checked yet). This requires a 2 gang box for mounting. October 18, 2011
Rated 5.0 out of 5.0 by I installed this product in a major hotel chain and they are very pleased with the low profile look. February 7, 2011
Rated 5.0 out of 5.0 by Kidde Silhouette CO Alarm This is the perfect product for anyone with a twenty foot ceiling. Eliminates the need for battery changes for nearly 7 years. December 10, 2013
Rated 5.0 out of 5.0 by Modern, compact, stylish, functional, durable The unit was easy to install in a 4x4 inch electrical box and the plug-in cord supplied with the unit made connection to the unit also easy. The blue LED indicator is intense which makes it easily to see from across the room. The audible alarm is piercing and unpleasant, which is exactly what I want in terms of a sound which notifies of pending danger. The testing instructions were clear and concise. All functions worked as specified in the instructions. April 3, 2012
Rated 5.0 out of 5.0 by Numeric readout, not just an alarm, great nite light too! Lights the hall with a nice blue glow once the lights are out. November 5, 2011
Rated 5.0 out of 5.0 by So far, so good..... Just installed the CO detector two days ago. Easy installation and I like the size/shape of it. Working fine thus far. Only issue is the indicator light is quite bright. Would like it a little dimmer during normal setting. On the other hand, it's a good night light! April 29, 2014
Rated 1.0 out of 5.0 by First one had a faulty battery. The battery wouldn't charge itself. Lo-batt alarm started going off 24 hours after the charge cycle. Will buy one more for it to redeem itself December 6, 2011
