Triplett AC Line Splitter and GFCI Outlet/Receptacle Tester with 5 Visual Indicators (ET200)

Ok

This appears to be substantially the same as several similar units I have or have used. The new thing (to me) is the GFCI testing button. If its not apparent from the picture, the thing that looks like a guard around the GFCI testing button isnt. Im not really sure why its there at all; the button protrudes a few millimeters and takes very little force to depress. So far, Ive successfully tripped a known working in-wall GFCI... and proved to my satisfaction that a GFCI-protected extension cord I bought for cheap from Wal-Mart is probably unsafe / defective(?). (If the GFCI light comes on, probably even for a moment, while connected to a GFCI-protected circuit, its probably time to get a better GFCI. In the case of the extension cord, the GFCI light stayed a bright, solid, ominous red for as long as I cared to hold the button down.) I dont have any out-of-code outlets or appliances Im aware of, so theres a slight question mark about the other functions; it does light the completely correct pattern for all of my known-good outlets, extension cords, etc.

This works well as a double check for your work. Not a replacement for no experience in wiring.

Perfect for homeowner or pro.

Works flawlessly and does not feel cheap. No regrets. Sometimes the lights are not clearly distinguishable under bright conditions but you just use your palm to give it some shadow and thats it.

Well built, works as advertized.

lover that theres also voltage probing points

Works well. No complaints.

A good addition to any tool box.

Works. Just about it really.
