Review on DEWENWILS Wireless Programmable Switches Receiver by Pete Norris

Our bedroom light switch is plugged into an unused socket so we gave that a try. Works great to fix the problem so we can turn the light on and off in the bedroom. BUT? Every time we turn on the light with one of the remote controls, our Christmas tree starts blinking. It's only 1 of 2 switches and my Christmas tree doesn't even have a remote control. So this is quite confusing for us. Not sure how he does it.
