This will tell you if you have power or various combinations of crossed mains wires etc and works OK but I wish I had bought the version with the buzzer. With an audible warning if there is power to the socket I do not have to keep checking at the consumer unit. Apart from that it is handy, sturdy and small enough to have in your tool bag.

Handy to have in your tool box.

This is simple to use ,but once you have checked the outlets in the house that will be the end of its usefulness You will then lend it out to someone else , after the second time it will be lost to you for good .
