Review on Nilight 5 Gang Multi Function Rocker Switch Panel: Backlit, USB Charger, Voltmeter, 🚦 12V Outlet, Pre-Wired - Perfect for RVs, Cars, Boats, Trucks, Trailers - Red (90124E) by Curtis Donjuan

This is definitely an opportunity to test your patience with device repairs before hooking it up to accessories. Almost all the wires came from the connectors. As soon as they touched them, they began to come loose. It is not possible to connect the main power cable from the power supply. To do this, you must select one of the radio buttons. The power is always on, I added a master switch to turn off the power. Appreciate having a volt meter on all the time. Using it as a switching device on a boat or something you don't use every day will drain your battery. I wouldn't recommend this to anyone looking to connect and use. Luckily I had the tools and extra connectors to fix the device. This is the easiest review I've written, unfortunately it's also the worst.
