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.

Great Buy!

Great product. I installed it in built-in cabinets that were installed in my office. It comes with a template, so you don’t have to measure or guess.
