Works like a charm. Good looking as plugs go. Easy to use.

I was almost ready to return it because it did not fit into the small metal wall box with the old BX cable wiring in my 1939 house. Someone suggested using a Wire-mold surface box with pigtails connecting to the ancient wiring. It worked and we love the new GFCI switch.

The switch with its multiple functions addressed ALL of my requirements. Its simple design allowed me to install it in the original electrical box without making any alterations.

Two units, both functionally useless. Trying to replace an old switch/outlet combo with new (gfci) one. Wiring line/outlet only (without switch) to test setup and wiring. Gfci tester plug says it is wired correctly, but both units trip immediately when powered or reset. Putting in a spare 2 slot gfci unit with the same line wiring (sans switch) does not trip. No instructions in either box (despite box saying they are inside). Online instructions here are for gfci outlets, not the switch/outlet version. Terrible experience and without proper instructions not even sure product is any good. Could be user error, but with no meaningful instructions, I can only go by what the tester plug says.

A vertical switch makes it clear whether it's on or off -- other switches are often horizontal, and for some reason I can't remember whether left or right is on!
