Review on KEING Multi Function Waterproof Volmeter Pre Wired by Jeff Swan

I've bought several different ones over the years this is by far the best. Wires are definitely a bit thicker than all previous periods, and separate fuses on each switch were also a plus. A very good quality. I divided the block into 12 volts at the top and 24 volts at the bottom. I connected 24 volts to the cigarette lighter and it showed voltage and it works great.
