Review on 🔌 Klein Tools RT250 LCD GFCI Receptacle Tester for 120V 3-Wire Electrical Outlets by Peris Holland

We are RV enthusiasts and have a wide range of electrical test tools. We've always relied on those mostly yellow three-LED socket testers, but this new Klein RT250 socket tester is completely outdated. Recommend that every home should have one of the RT250. We have a few and we gave them away. The display explains in words if there is a problem and the red/green light is on. The display even stays on for a while after the device is unplugged, so you can see the results when the plug is out of the way or upside down. I love this device. thanks little one There is no competing similar device.
