This outlet has to have the worst connection design I've ever used. The screws are loose unless you tighten them when you're done. This means that they go in and out very easily depending on how gravity or some other force is acting on them. To make matters worse, there is almost no room for wiring on the back of the screw. So you have to hold the socket at a weird angle and hope the screw comes completely free to have the maximum space and then you have to somehow fit the loop of wire into the too small space. And remember that the screw is loose, so any pressure you put on the wire to push it in just pushes the screw down and prevents the wire from getting underneath. could not move freely, it would have made a big difference. And so I'm forced to use the holes on the back, which isn't the best way to connect the outlet as the wires are more prone to loss. Oh, and the exit is extremely deep. Better have plenty of space in the box.
