Sperry Instruments GFI6302 GFCI Outlet / Receptacle Tester, Standard 120V AC Outlets, 7 Visual Indication / Wiring Legend, Home & Professional Use, Yellow & Black

Its fine, button could be a little easier to push

It was working great until it gave me. Reversed ground/hot. When I checked, it wasn’t reversed. Could be dangerous to someone not familiar working with electricity.

One of the LEDs is flakey. Wasted an hour until I figured out it was the tester giving bad results.

Use it every day for my inspection business, display lights are clear and easy to read

Just what I needed.

As other customers stated, difficult to read as light bleeds into the other area. But even bigger issue was clear wrong reading as we have a socket (with a metal decorative plate) where we know the grounding is an issue and this thing shows All clear. This socket, we can actually feel light current on the plate or on a aluminium body laptop.

TESTED A WALL SOCKET AND THIS DEVICE INDICATED A LOOSE GROUNFD WIRE.

Average

It does its job

Ive already used it for my GFCI monthly test and discovered bad outlets. Its small and straightforward. No guesswork, no electrical knowledge needed. Just match the lights with the chart on the face and bobs your uncle.
