Review: Works as Advertised - Worked as advertised. Used to to add an exhaust fan heater to our bathroom. Rather than run a new line to a switch I just put this in series with the wire. I’m only triggering it from about 10 ft away, so can’t speak to the length of signal distance. Quality seemed decent, but there’s always a thought in the back of my mind that it might not really be 30A rated. I’ll let y’all know if my house burns down.
Review: Works 1st time every time! - I am stunned. I was only about 40% confident this AC remote light switch would work. It is a game changer. I bought it to turn on a security light outside my woodshop. It works perfectly! Range from the house is around 100 feet through several walls. I mounted the receiver inside the shop in the peek of the roof about 14 feet high and it works first time every time. However the two remotes each have their own channel. It is very helpful that the remotes are interchangeable so they can be left in 2 different locations to turn the light on with one and off with the other

### ⭐⭐⭐⭐⭐ Works Very Well
*by C***O on November 4, 2023*

We have this on our well pump and it's great. We also have it on our water intake pump which is about 100' below our house and it works great. We are very happy with these and the 2 remote units don't share the same remote code so you don't accidentally turn on another pump with the other remote. They are easy to install and last a long time.
