I bought one of these on a previous deal. It is very cheaply made but I keep it plugged in in the kitchen area (yes, it's 110) and having temp and humidity is nice anyway. Hopefully it will alert if there's CO but I wouldn't count on this for that. Also, the alarm is not very loud so don't count on hearing it upstairs if you're down or vice-versa.

FYI this company buys 5 star reviews. After I purchased one of these I got a postcard offering me money back if I rated the product 5 stars
