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.
