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

works great

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

Not worth it the ground prong broke off

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.

Not bad, good tester

I thought this can identify accurately the live, neutral, ground. But it is stated on the Manual that it cannot distinguish which is ground and which is neutral. The dim LED as well is confusing based on the table.

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

Easy to use

This product is simple to use, not complicated at all. I purchased to test my outlets for grounding connectivity. I have purchased grounding sheets and needed to make sure my plugs and power bars were properly grounded so I could get the full effect. I highly recommend. Clear instructions on the item as to what the light mean when plugged in as to what you are looking for. You only have to plug in and push a button. Them the lights come on to tell you if it is grounded correctly or not! Great product for the money paid! I would buy again just to have a extra one in my tool box .

Dont know about the accuracy, but very easy to read and told me what I needed to know.
