Taiss GFCI Outlet Tester New Advanced Receptacle Tester with Voltage Display 48-250V Power Socket Automatic Electric Circuit Polarity Voltage Detector Wall Plug Breaker Finder CAT II 300V TA106B

Great unit

Great voltage tester, quick and accurate, however the ground pin seems to be a design flaw. Mine has fallen out and wont stay in place. Going to try super glue since I am out of my warranty period. Wish me luck cross fingers

Easy to use and analyzes circuit correctly. Is a little large, causing issues in tight-fitting locations, otherwise, great tool...

I have to test GFI Outlets on scissor lifts and boom lifts every day. I used to prong my meter to test 10+/- units daily. After using this, it saves 20+/- seconds, every inspection. That may not seem like much, but it makes the job 10x easier.

A Perfect easy to use and very handy tool. I love it.

I have no idea as to accuracy. It’s easy to use, just plug it in. All it shows is voltage. Instructions are incomplete, and only tell what it’s supposed to do; not HOW OR WHY. The instructions should include complete operating information, and why!

Works great. Easy test voltage, wiring, and ground fault.

Great value, I recommend it. Works like all the other North American outlet testers but includes a GFCI tester (just push the button and it simulates a ground fault, tripping the GFCI unit) *and* it includes an LCD Volt meter. We have both grid power and solar power and I like to know what the voltage is - this makes it easy, just plug in the tester. Beats dragging out the Fluke multi-meter and sticking probes into the outlet.

Not bad, good tester

Fast shipping, excellent tool
