Suraielec Wireless Light Switch and Receiver Kit, 15A High Power No Wiring, 100ft RF Range, Programmable Remote Control, 3 Way Wall Switch for Lamp, Ceiling Light,

Initial Impression: This system is really cool. If you have DIY experience with installing switches and plugs, this is very easy to install. I just pulled out the old switch and determined which wire on the switch was hot ("line") with a voltage sensor. I turned off the breaker for the circuit and just followed the instructions. The switch/receiver is relatively small, so it fit readily into the existing wall box. I like that the wall mounting plate has holes and screws to mount to the switch box so the new switch can be installed right on the existing box. Both switches work well, and the lights turn on and off surprising quickly, event from the remote switch. I had put off running three-way switch wiring for years. I'm really glad I thought to search for this type of device. It really saved me a lot of time and money.

Works great. Easy instructions

Simple to install, works great !

If you're here reading this, it's because you're thinking about this, and I cannot iterate enough just buy it, it will (probably) solve your problem While it's a 3 way switch, it's actually almost a 4 way switch if you account for the base that receives the signals and actually does the switching - there's a small illuminated button on it that toggles the switch on/off, which is practically another switch. In my application, this is mounted near my electrical panel which is in the same area as the switches, and it's right next to my mud room door, so I use it just like the other two switches. Speaking of the other two switches... this thing has freed my mind of traditional electrical in so many ways. You don't need any wiring at all to add a switch. That means you can add a switch in your attic, add another light in a dim room, add a switch to your bedroom to control your outside lights, put a switch in a place that you can't safely/practically run wires, really the sky is the limit (and the range I guess, but, I haven't run into that limit). You can't even call an electrician to ask for a quote to add a 3 way switch for the cost of this. Not to mention, wiring a traditional switch into a place that doesn't have one already is a multi-pronged job. You need to patch and re-paint drywall, possibly in multiple locations, run the wiring, connect switches, add the 3rd switched wire between the two, etc. This could quite literally attach to your wall with a command strip, wire the switching relay in at the source, and you're done! It took me less time to add to my circuit than a standard on/off switch would have, I'm not exaggerating! An added bonus - this needs to switch the hot wire, not the neutral wire. As such, once the relay is wired up, you can turn the entire downstream circuit on/off using the wireless switch, so if your application like mine is to put 15 lights in a basement, you can use the overhead lighting, turn the circuit off wirelessly when you're about to handle the live wires, turn it back on (wirelessly!) once you've done it, and move on to the next one. Super handy, I really cannot say enough good things about this. The absolute only complaints I have is that it's only rated to 15 amps, and, the wires you have to connect to are stranded wires, not solid copper. I'd recommend using wago wire connectors over the included wire nuts to preserve these connections, as they're a little short as well. Someone has also pointed out to me that it may be difficult to wire into existing electrical boxes (IE your existing switch box that's behind drywall) due to using a locknut style connection through the knockout rather than a push-to-fit.

will buy again
