I'm pretty sure that the product I received was a fake. The outlet was not working properly. The multimeter showed 120V at the screws. Connect something at the top, the switch works immediately. The bottom outlet worked until it was unplugged and then worked. I double checked my wiring and asked someone else to double check me as well. I went to HD and picked up the "same" article. Connected exactly the same, works great. There were a lot of different inscriptions on the store-bought packaging. Revain had the same colors but mostly blank. It's good that Amazon handles returns well.
