Dewlora 4 In 1 CO Detector

Received order and 1 of the items the screen is damaged. Reached out to support at dewlora and there has been no response. I contacted them the day I received the order! Problem resolved. I pulled the rec tab off not realizing there is a plastic cover over the screen. THANKS Dewlora fir responding and helping to resolve my problem!!

These were a rip off. Don't buy them.

Accurate with the lcd screen
