Summary: The directions could be a bunch clearer --I can only get one of the slots to work when I plug in my devices ---I would like for you to tell me if I can only charge one item at a time---I guess if you answer this I will be able to tell what you think of your own product.
Summary: I ordered the 4 port hub, instead of the 7 port one, not because of the price, but, because of the size. I have a new Dell Win 8.1 tablet that has a micro USB port (1 only) and it does not put out enough power to power a portable (2.5") external HDD. I have my massive music collection on a 2 TB drive and needed something to power that drive, thus, the powered adapter. I use a micro USB to standard USB converter and plug the hub into it. Then plug my HDD into the hub.
Summary: Almost spent $20 for a 4 port without a power supply. This one cost $12 and has a power supply. Also has long cable lengths on power supply and USB cable. And a on/off switch. Great price and lifetime limited warranty.
Summary: I have put a lot of hours on this Gear Head usb hub in just the last four days and am very pleased with its operation. I've had several hubs in the past and have had problems with them so I was a little concerned about using another one, but really had no other alternatives. My laptop has only two usb connections although I really need at least four.
