1 out of 5 eggsFailed to detect

Pros: Packaged as an alarm it may very well work at high levels. My personal experience with low levels making me and co workers sick, no way. I bought this same brand at Target because I wanted it then, it's being returned.

Cons: failed to detect CO at work during a bad week of exposure. CO from bad heat exchanger detected by other brands and confirmed by the gas company

Other Thoughts: we were dealing with levels from 10ppm to about 18ppm measurements from gas company detectors.

5 out of 5 eggsExcellent home detector

Pros: The readout panel allows you to get all the info you want at your finger tips. The display is very responsive. One very useful feature is the hide-able cord. You can plug it straight in, or mount it and plug it in around a corner - quite useful.

Cons: The reaction time of the overall CO sensor seems to be *slightly* slow. The pause is only 2 or 3 seconds, and would not prevent me from recommending this product - its very nice.

Other Thoughts: I purchased two of these devices, both behave as expected and exactly the same under CO testing. I have access to a testing facility, and compared them to 6 other detectors. The "CON" listed above should not dissuade you from buying the product, since the other detectors I was comparing them to were industrial grade with air-pump assists. This is a great *home* product.
