Work's, September 14, 2009

Price is good. Replaced the units in camper that very hot at times and no false alarms.

No Tabletop Stand, March 30, 2009

I ordered two of these combo CO / Smoke Detector sets, the CO detectors are supposed to come with a tabletop stand which would eliminate unnecessarily drilling holes into walls, neither of the two sets I ordered included the stand, what are these, reject sets ???

Smoke & Carbion Monoxide Detectors, June 23, 2008

Kidde Smoke and Carbon Monoxide detectors are of high quality. This name brand is sold in my local stores, however, the prices are much higher than at Amazon.com.

Hard to Know, March 16, 2007

Since I've had these 2 alarms, I've apparently not had smoke nor carbon monoxide in my home because they haven't gone off. Kinda hard to assess how they work until I have one of those problems but they both are easy to set up.
