I wanted some USB sockets and saw some good reviews so I bought 2 packs of these. Installed one and the USB ports worked fine for a day or so, then it started pulsing power through the USB ports every few seconds instead of charging continuously. Took it out of the wall, checked everything, put it back in and it worked for about an hour before it started pulsing again. Removed it and installed the second of two packs to see if it would work and the USB ports on this one were dead. Went to a different outlet and tried both, same results: 1 pulsing charge and 1 with dead USB connections. Ran to the local hardware store and bought a Leviton branded version of this outlet as I was still curious if that was the problem. with my wiring or these outlets. I installed Leviton in the original place I installed these Dependable Directs and they work great with no issues, so it all boils down to these cheaper outlets being junk. tl; dr Save time, headaches and money in the long run by buying the best branded product from the start.
