This review is from: AnkerŪ Uspeed USB 3.0 10-Port Hub with 12V 4A Power Adapter [Apple Style Aluminum Hub] (Electronics)
Very happy with this product. It provides ample power and works at proper usb3 speeds. Ideal for my iMac so I can have a couple of different printers, sound cards, graphics tablet and card reader plugged in all the time, ready to go.
Update- - Feb 2014. The firmware needs to be updated on this unit for full compatibility with OSX Mavericks. The unit still works well, but will not always "sleep" correctly. Firmware update is available but you can only update on a windows machine (which I do not have). Not good. Units currently being sold have the updated firmware and work very well.
