Functions. No trigger,need relay for car install
Functions,but will not turn off. No remote wire,just positive & negative. Need relay to install correctly to use on-board fuse. Or connect to remote only to view voltage use. No instructions.

Prompt arrival
It works as it should. I have a 500 amp fuse inside. It came with a 100 amp fuse already installed. I have heard too many horror stories about being a "team no fuse". I'm glad mine came the following day after ordering it. The voltmeter is nice and clear. Although I won't keep it on all the time, just to show off when I have my hood up at gatherings 😎
