Customer Reviews
Exactly as expected 
2008-05-15
This alarm was delivered on time and as expected from Amazon.com. I have not yet found out the battery life because the product is new. The alarm sounds if you insert the batteries incorrectly and there is a timer that makes the alarm sound after 7 years when the product is due for replacement. The device comes with a stand so that you can place it on a flat surface no higher than 3 feet above the floor rather than drill holes for wall mounting. I have high expectations for the quality of this brand.
Questionable reliability 
2008-05-10
When we bought our house two years ago, two of these were just installed by the seller (due to the new law in Massachusetts). After about a year, one of them started displaying randomly-on segments on the LCD, making the display useless. Presumably the CO alert still works, but who really knows? Then, the other one needed its battery changed, and after I put in the new set, it too has a corrupted display -- but worse, the alarm is stuck on, so it's pretty much broken.
And even when they were working, there's another annoyance: the green "Operate" light blinks brightly once a minute, which takes some getting used to in a bedroom when you're trying to fall asleep.
I'll be shopping for a different brand for replacements
Easy to Install; fair price.

Good quality, reputable company. Battery operated detector is the only choice if you want protection during a power outage.
How do you rate null? 2008-05-01
Of course, in this case, null is a good thing. We bought two of these and they are reading zero. Had to downrate because of the two, one had a display that was defective (fixed itself after a day or two). Otherwise a great feature set. Be forewarned that these devices are programmed to self-terminate 7 years after firing up.
Great product 2008-04-27
This monitor is very easy to install and gives a good,easy to read display. A product that needs to be in every home.
Misleading List Price 2008-07-24
Homedepot sells for $39.99 and in store on-sale for $19.99. 44% saving is a joke.
It went haywire after a year. I tossed it.

One day it started signaling for no reason. I changed the batteries and it continued to randomly alarm. This happened in June. We are only using electricity and we don't have cars running in the house ;-).
Ours didn't last.
CO detector 2008-06-07
Looks good easy to install and understand, good price. Don't know if it works; no CO in the house yet.
CO detector 2008-05-27
Top of the line in battery operated products. Found them much cheaper in three local stores. Look around.
Works great 2008-05-22
I put the battery in it and did the test and it seems to work great.
