Bought 3 units and they all work but 2 has loose pins/legs so I opened them up. Found out there is a small tab used to hold these legs in place. One of the ground pin has broken tab and the other has crack line and almost broken off tab. These seem to be poorly designed or material defect or both. Might help if the package has these plastic cups to protect the plug heads while in transit to store. Had to hot glue them to help firm up the legs some. Crazy glue & silicone adhesive do not work on this plastic tab.
I bought these taps because of the surge protection. There are 3 plugs on each side and 2 convenient USB connections in front. The unit connects to the wall outlet via one connection. I like the blue led glowing at top to indicate its working condition.
I would have been happy with purchase if not for the defect mentioned. Got them at good price but 2 out of 3 fails would deter me from buying them again. Look at pictures I uploaded & decide for yourself.
