Kidde KN-COPP-B Front Load Battery-Operated Carbon Monoxide Alarm with Digital Display

Great product. It has a "kickstand" so it can be placed on a table or screws so it can be hung on the wall. The digital display is recommended for CO testers. You can change batteries without removing the tester from the wall. A leading consumer testing magazine recommended this one.

I often buy from Amazon because it is easy and usually cheaper. However, I found this item at The Home Depot (reg. 39.99) on clearance for 19.99.

This is a good, high-quality device, with a clear display. The display is a little smaller and contains a little less than the earlier version of this same detector (of which I own two), which is the only reason I didn't give it 5 stars. But it works well, as best I could test it (using the vent from my gas oven), with a clear, easy-to-read display. The ability to change batteries without dismounting it is a plus. I bought this model (earlier and current versions) because it was highly rated and a good buy according to Consumer Reports, and it lives up to that review.

The alarm went off as soon as the batteries were installed. After trying all suggestions in the manual for turning off the alarm, I removed the batteries and returned the product.

Easy to place where ever you like, as it's battery powered and you do not have to plug it in. The one's that plug in I avoid as placement becomes a major inconvenience.

Product worked exactly as advertised. Very good directions. Well made. Should work for years. I liked the fact that it's battery operated and could put it anywhere.
