Tools and Hardware Reviews of First Alert GCO1CN Plug In Combination Explosive Gas/Carbon Monoxide Alarm with Battery BackupCustomer Review: First Alert GCO1CN Gas/Carbon Monoxide Alarm Summary: 5 Stars
Seems to work ok. No false alarms. I assume it's working but I haven't tested it with the gas stove, etc. I installed it on upper wall for natural gas detection as per instructions. The extension electrical wire plug is handy. I think its a good buy.
Customer Review: Sense of protection Summary: 5 Stars
I had installed it in the basement about 20ft away from the gas heating furnace. It was installed about a month ago I have had no false alarm so far. Smoke and Co alarm in that area gives me a great sense of protection.
