Review on Waterproof 4 5 150V Automative Motorcycle Voltmeter Interior Accessories by Will Murphy

I went through 2 of these in less than a month. There are NO instructions on how to connect it so I had to search the internet to make sure I connected it properly. I did it and they died anyway. They are not entirely accurate as according to my good handheld voltmeter it had dropped more than 2 volts. They're also a bit bigger than most, so now I have a big hole in the dashboard for the others to fall out of. Don't waste your time and money with this junk!
