Splenssy Transmitter and Receiver 433Mhz, Smart Home 433Mhz DC 12V 1CH Wireless Remote Switch Relay Universal Remote Control Switch Modules and RF Transmitter Remote Controls (2 controls)

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!=.

It doesn't work over about 20ft away even with a clear line of sight

Very impressed with compact size, ease of installation, flexible modes of operation, and excellent range. Good quality remote.

I like it. I can now switch on/off remotely my extra led light in my motorcycle. I don't know what maximum is range for remote I try 60, 70 meters and it works! My alarm remote range is max 20 meters 🤦🏼‍♂️

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.

Item arrived with no instructions. As it needed to be programmed before it could be used this rendered it completely useless.Would have sent it back for refund but didn’t open it until after the return window as waiting for other parts for my project. Will ensure I open everything on the day of arrival in future!
