use for under the hood on battery to connect 0awg with factory wire ended up not using because i did not want to cut factory wires to install, did test the led and lights up nice , prob would be better if battery was installled inside the car

Well built looks nice and good price. The voltmeter is fairly inaccurate, I tested the same contact points with my fluke multimeter and showed a difference of almost 2 volts, still looks nice though and does its job just don't rely on it for an accurate voltage reading.
