I own 2 others that are the mini versions. I like this model for its robust construction, durability, and ease of use. It also has a "momentary on" setting that the others don't have. The settings I use are "on/off, toggle, and momentary". These relays have an unlimited number of uses. Just in the camping category you can pair it with a rechargeable power tool battery and remote power a camp light, a radio, or even a siren paired with a flood light if you're in a sketchy area. I often pair one with a Harbor Freight 24volt power tool battery and a Harbor Freight LED Flood light. Instant whole camp illumination from 200 feet up the trail. Awesome piece of electronics and that's a welcome change from the other Chinese junk the world's being filled with. Review: Easy to install. Works great on boat 12 volt system - I installed a set of backup cameras on my boat that required 12 volt power and had to wire them under the deck. I needed an easy way to turn the power on and off. I installed this in the bottom of the boat in the back, I can easily turn them on and off now from the cab of the truck pulling the boat. Very nice and super easy. My recommendation is to figure out how you want to connect things and buy the connectors you need at the same time. This does not come with wire or connectors and you may need terminal connectors if going to the battery, and probably some 14 ga. Wire. It was easy once I had all the wire and connectors. The key fobs are pre-programmed, so once I got everything wired up, it just worked. ## Features - HIGH POWER LOAD: The Relay adopts 40A relay, which can load high-power electrical appliances to ensure long-term stability control (Note: max load: 30A) - STRONG SIGNAL: Adopts RF technology, it can pass through walls, floors and doors, control receiver from any place within a reliable distance.
