“Bought one of these Tester Plug's just so I could be absolutely sure that my Sockets were definitely correctly grounded.

Easy to use, worth the money just to be sure.”
“Does what it says. If unsure whether you have proper earth in an older property this is very easy to use. Just plug in and if all lights on it reassures you to know you will be grounded.”
