This works great and is very easy to connect. The price is incredibly low. The device has some limitations, which are quite understandable considering the price. A better device would have: - a coded transmitter/receiver so each set is unique - 14 or 16 AWG wires would be better suited for the 15A current rating than the 18-22 AWG wires available on the market are. - a relay with a socket that can be swapped out like any other automotive relay, or a solid state design - a relay or logic to maintain the on/off state when power is removed - some level of protection against that ingress of water. - A fuse holder and a 15A fuse can be supplied - Mounting hole for mounting the case. I don't think it's reasonable to expect all of this for $15, so it's a great deal.
