Handy Tool
This tester could save your life. Used in an RV with no issues - the tester showed all was well. Using the same tester in a house, it gave an indication of potential wiring issue, as the voltage showed 30VAC on first check and 123V on a subsequent check. It will also indicate ground issue, reverse polarity. Glad to have bought.

Excellent tool for testing electrical outlets
This tool makes testing electrical outlets quick and easy. It is especially helpful to locate GFI outlets that are chained together. The tester can purposely trip the GFI and you can locate the downstream outlets that do not have power. The only drawback is it can be difficult to remove it from some outlets.

Best GFCI Outlet Tester Available
This review is for Klein Tools RT250 GFCI Outlet Tester with LCD Display, Electric Voltage Tester for Standard 3-Wire 120V Electrical Receptacles. This is the best outlet tester I have seen so far. I love the backlit readout and that it gives you the voltage information too. All the features, including the GFCI test, work flawlessly. I have never had a Klein tool that I have been unhappy with, and I find this tester to be a great value.
