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 😎
