Simple and reliable
This Klein outlet tester is a very handy tool to have around the house. It’s extremely simple to use—just plug it into an outlet and the indicator lights quickly show whether the wiring is correct or if there’s a problem like an open ground or reversed wiring.The built-in GFCI test button is also very useful. It allows you to quickly verify that GFCI outlets are functioning properly and trip when they should. I used it to check several outlets around the house and it worked exactly as expected.The build quality feels solid, which is typical for Klein tools, and the printed legend on the front makes it easy to interpret the light patterns.Overall this is an inexpensive but very useful tool for homeowners, DIYers, or anyone who wants to quickly verify outlet wiring and GFCI protection.
