OAONAN GFCI Adapter 15 Amp 3 Prongs Grounded, 5 Years Warranty, GFCI Plug Portable Plug-in Ground Fault Circuit Interrupter to Protect Electric Safety for Pressure Washer, Hot Tub, Air Conditioner

Good product works well.

Works as advertised!

Have an older setup and when I went to install a new dishwasher, I wanted to add a GFCI outlet, but there was just not enough wire and the current outlet was a split for dishwasher and garbage disposal. Thought I would give this a shot and it works perfect for the addition of the new dishwasher.

The device seems to be of good quality and works well, I haven't had any problems so far.

While vacuuming my flooded basement with a wet/dry vac, I suddenly realized I was standing on damp concrete while plugging and unplugging the vacuum and flipping the switch whenever emptying the canister. Maybe it was imaginary, but I suddenly thought I felt some tingling in my hand so I realized I needed to buy a GFCI Plug to hopefully protect me. The GFCI quality does feel as if it is made with cheap plastic, but when plugged in and the test button is pressed, it does trip the GFCI. I can only hope that it really works.

Has to be plug in to a outlet works great

I shorted it 3 different ways, and each time it worked, including GFCI tester tool. If you're using a multi-outlet adapter for all your fish tank equipment, consider this item. It can save your life!

I occasionally use a 120V to 100V stepdown transformer with a cooking appliance or a tool such as a spinning knife sharpener purchased from Japan on our patio.The transformer is connected to a GFCI AC outlet but the load side is not protected by the outlet's GFCI.This adapter is a perfect fit to the transformer and the pilot lump helps check the status.
