Looks like a high quality GFCI socket but I must have a broken one. One of the screws holding the white wire didn't tighten the plate inside. The screw just turned freely even though it was connected to the plate on the inside. The other screws properly tightened the plate connecting the other power and ground wires. Of course, if one doesn't work then it's all useless, hence the one star rating. I ended up paying twice as much for a similar outlet from another manufacturer at my local big store. I returned it and got a refund and the manufacturer said they would fix the problem to make sure it didn't happen again. I would try them again in the future.
