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

Easy to use

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

voltage incorrect

Its a nice thing to have in the tool bag

Great unit

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.

Works good and is accurate. Im docking one star because it really needs to show voltage between hot and ground, and neutral and ground. That would be helpful with troubleshooting.

Fast shipping, excellent tool

Inaccurate voltage reading, The LCD digital voltmeter consistently reads 6-Volts low. I compared three different fluke meters all confirmed that theTaissGFCI Outlet Tester was unacceptably inaccurate. Accuracy is important when checking outlets one can quickly discover wiring issues. I put a label on my device tester reminding me read 6-Volts low. I recommend that if line voltage accuracy is important that you do comparative testing.

It knows more than the electrician.
