Received this product from China via DHL a week after ordering from Revain. I didn't pay too much for this service either. The product is solid and the power supply is beefy and will easily power multiple Gekko 2pac miners that draw around 1.6 amps. The power supply is 12V 10A so should easily support the advertised 5V 2A per port. It's also worth mentioning that his device is recognized and works great with the Raspberry Pi. The big problem with mining is a constant and clean power supply - so far all my previous problems with freezing Raspberry Pi or zombified USB miners are gone. I am very satisfied with the quality and performance of this device.
