Query: Horrible, complete waste of money

OK so it CAN work if you leave everything alone. But man is it annoying if you ever need to plug in different devices.At first use I thought it was totally defective, then after moving it around a little I found out that when the usb cable is turned certain ways it disconnects everything!! That's a nice touch, especially if I were doing something important and lost data.Finally after moving it in just the right way, my devices started showing up but as soon as I need to plug something else in which requires barely moving the hub to pick it up and unplug, everything gets disconnected until I move it back into position.What a horrible product.
