Any problems with low voltage? This will tell you. Checks wiring on receptacles and gfci receptacles. Love the fact that it also shows what your voltage is. Had a jumpered receptacle once and power was low due to corrosion from another. This would have told me everything from the start. great tool to keep on hand.

Great GFCI tested
This is a very nice GFCI tested. The display of the current voltage is a nice additional benefit.
