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

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!

Love it

Detects problem in GFCI switches and normal wall outlets - works as advertised

This works great, very helpful. I love the fact that it also shows you the voltage at the outlet.

Me ayuda mucho con las instalaciones en mi casa, y a veces en el trabajo. Con esto ya deje de usar muchas veces el multimetro solo para estos casos de medicion de voltaje del toma corriente.

Very good product very handy

It does what it’s supposed to do, but the display is a little hard to read. All the other functions work just fine.

If you think you are having AC electrical this is handy tool to have not does it show you the voltage it also tells weather it wired correctly and if the grounding is wired correct.. I had a problem with some shop LEDs and couldnt figure out what was going on till I had this handy tool and it showed me the lights had floating ground issue which was an easy solution.

It is simple enough to use to check the outlet for the voltage readings.
