2 Pack Carbon Monoxide Detectors,CO Detectors Battery Powered,Carbon Monoxide CO Alarms with Light&Digital Display for Home,Bedroom,Kitchen,Office

We had a 10 year product and it finally died. But it died in a scream of agony and of course these only come in the middle of the night. The beep sound makes my dogs nuts. They bark. We get nuts. Obviously it was time for new ones. I was surprised at the price and the size. They are small. We are very pleased with this purchase and look forward to not being waking up by an alarm announcing their deaths for many years to come.

The flashing light is bright, so beware of installation location.

These are easy to mount and set up and far as I know they work. No issues getting to battery or mounting to wall. However, a negative is that as long as the battery works it flashes a bright green little light. We had to tape over that on the bedroom one because it’s a bright and regular flash. So that’s quite annoying in a room where you watch tv in a darkened area, or where you want to sleep.

Works as advertised

I guess we won't know if it works, until it does. My comment is about the blinking light it emits. So, before you mount this, I would recommend you not mount it in a bedroom, or anywhere you want it dark. It is like a strobe. I would think if you are prone to seizures, I would definately not put this in a dark room where you sleep. It is very bright. Not sure why it needs to flash, but it does.

Have been able to have peace of mind having these on the case helping us out

Very happy with these detectors. One thing is the light that blinks now and then is very bright so it can be distracting if mounted in the bedroom, I put mine in the hall just outside the bedroom. Very happy with this purchase.

I feel safer knowing I have these in our bedrooms. My only issue is the the green light that flashes every few seconds is very bright. I had to move it so it didn't keep me awake lol
