The product worked great for making the lights in the bunkhouse of my RV remote because the kid and wife couldn't reach them to turn them on. The wiring directions that came with them stink.

I use this device to switch on/off a water pump remotely. When your one person working on projects having something like this device helps a lot.

Fast fix for a 22 year old lift master that the Rf quit working on, just need a 12v dc supply and yer good to go. Paired the two remotes and set it up for momentary operation, easy peasy. Not the best for security but until I take the opener apart and troubleshoot the control module suffice it will.You can even swap the little circuit boards from the remotes so it will clip onto the visor or whatever.

Used these to replace oem remote system. Was not easy digging into auto wiring. Suggestion-extend antenna to get any range
