These are amazing! Awesome alternative to breaking seal and running wires through bulkhead! Very responsive. I figured there might be a delay from switch to unit but it’s basically instantaneously! My only gripe would be that it doesn’t come with an inline fuse to put in between unit and battery. The fuses are cheap and not hard to install. The harnesses, plugs, and wires are all great quality. I ended buying some of their 8 ft extensions to add due to my truck being long and I installed aux reverse lights on rear of truck.
Works exactly as described. Seems to be well made. Great option for a controller without having to put wires through the firewall. Bluetooth connects easily too.
