Review: Works Great Save Lots of Walking - I have an Eco-Worthy Solar Controller 155 ft down a hill where my well is and I wired this switch to turn my pump on or off remotely. It fit nicely inside the box, I drilled a hole in the bottom for the antenna to stick out. I no longer need to walk down the hill to turn it on and off.
Review: Eat your heart out, FedEx - Not only FedEx but also some other delivery guys have the annoying habit of ringing the bell followed by leave the package and run. If you want to enjoy an afternoon siesta that will be precisely the time when they come so we had to disconnect the doorbell. Of course, that was a poor solution because you need the doorbell for all the other occasions. Here comes the white knight: a remote-control switch. It really solved our dilemma beautifully. This RCS is built to inspire confidence and, even more importantly, it has a good range so even when you need to switch a connection inside the garage you can do that from the comfort of your armchair - providing that you don’t forget where you put the remote. The installation is easy, especially if you do the connections right. I have to admit that initially I taught that I had a bad unit because I made a wrong connection. You need to connect the transformer output with a new wire to the input of the RCS and the existing wires to the output of the RCS. Essentially, if you do it wrong the green light does not come on. And in the end, they all lived happily thereafter...

### ⭐⭐⭐⭐ works
*by J***L on September 18, 2022*

The range of the item is great, ease of setup is great, only problems I had is the first one would not pair, but the seller quickly sent a replacement, but the other problem that needs to be noted is if you are to close to the receiver with the remote it will not work. I used it to power on or off a kids power wheels truck and noticed when the truck was running and got close I couldn't power it off and had to run and grab it and cut the other power switch I have to stop it. I thought I had gotten another bad one but found out if it is on under a load and to close it will not work.
