4.0 out of 5 stars Good little radios, quality control could be better
By Jerry on March 7, 2017
I bought these modules to interface with the Etekcity zap5lx wireless outlets. The modules i have used so far are working just fine. The only issue I have with the modules is that on half of the receivers there was a solder bridge joining the antenna socket and the adjacent coil. When you install an antenna (these units do need one) you should fix this bridge so it's not a show stopper. Using them without fixing this may have un predicable results.

5.0 out of 5 stars Easy to use and set up - do you really need complex packet-based Tx/Rx?
