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.

Simple and easy to use yet Amazing precision!!!
I picked up the Klein Tools RT250 GFCI Outlet Tester to help check a few outlets around my house, and I’m honestly impressed. This thing is super straightforward, just plug it in, the lights pop on, and you instantly know what’s going on with the wiring. No guesswork, no complicated setup, just clear results. The display is bright and easy to read, and the built-in GFCI test button is a lifesaver when checking bathroom and kitchen outlets. It helped me identify a miswired outlet in an older part of my house that I never would’ve caught otherwise. For something at this price, it feels durable and professional like something an electrician would actually use. If you’re a homeowner, DIYer, or just want peace of mind about the electrical safety in your place, this is a solid buy. Fast, accurate, and super easy to use. Highly recommend!

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.
