Review of combustible gas detector/alarm
Unit was easy to use and easy to read. Was a bargain and seems well made. Great safety measure if you have propane or natural gas use in an enclosed area.

A piece of mind with kids in the house
I bought this because the toddler in our house likes to turn buttons and there’s been a couple times that we did not know the gas was turned on on the stove. It does take a lot of room for your outlets and my kitchen is limited on outlets. We did turn the gas on the burner to see if it worked and it did.
