A very simple tool that picks up on voltage quite easily. The length of the wire is well sized for most cases. My only complaint is that the rubber warp on the handles of the ground prong managed to work their way off rather quickly, but that didn't affect the functionality of the tool. Definitely worth the price point and has helped me diagnose many automotive electrical problems.
