Review on KIB M21VW Micro Monitor System by Marcus Barlow

I really only needed the circuit board but I liked the gray buttons so I installed the entire faceplate. It literally took about 30 seconds for all of my tank monitors to start working again. Can not complain. Possibly the easiest camper repair I've ever done and nothing at all. Didn't even need a screwdriver. Works great now I have to clean that black tank because it shows full but the amazon covered it. Couldn't be happier.
