Review on X Sense Monoxide Standards Auto Check SC01 by Steve Linquist

Good product. The only thing is my friend wouldn't let me install it in the bedrooms because the light flashes every 60 seconds indicating it's still running. I haven't noticed it in common areas since I installed them so it wasn't bothersome but when I kept it in the bedroom waiting to be installed you could definitely see it in the dark. Not suitable for sleeping. If you have a new construction (I don't), the codes may require you to have alarms that "talk to each other". Not a problem for me but good to know when shopping. The instructions are pretty simple. For now I would buy again.
