## Customer Reviews

### ⭐⭐⭐⭐⭐ Very well priced remote control parts
*by S***S on 30 January 2022*

This works just fine for my application. The only issue was that my setup needed to be enclosed in a metal case and therefore the antenna supplied was no good. I modified the board to use an external antenna which is quite straightforward with basic soldering skills. The external antenna also extends the range to around 100m but ultimately this will depend on the surroundings.

### ⭐⭐⭐⭐⭐ Excellent
*by I***N on 2 October 2022*

Simple to configure and connect, good coverage... Definitely needs reliable full 12v psu and good fob battery to achieve full range. Used alongside wi-fi switching as contingency for loss of network. hard to beat for the price!=.

### ⭐⭐⭐⭐⭐ Really like this switch.
*by M***B on 4 December 2023*

Really good little switch, and very versatile. Doing the job well.
