Works well
Size: 6 Outlets, Style: Desk Socket - White
It works well but I've been having issues with the USB slots because it seems like it is not providing consistent power flow. Otherwise it works fine and the mounting kit is a nice addition

Doesn't work as advertised.
Size: 6 Outlets, Style: Desk Socket - Black
None of the 4 USB ports were supplying power. The merchant was extremely courteous and apologetic and offered full refund. I received the refund promptly. Merchant cares about their customers' satisfaction.
