Bests & Worsts Reviews from Amazon

I just received this item and it does work, but use caution when using it with external hard drives. It seems that any action, such as turning on or off a switch, as well as plugging in or unplugging a device from any of the other ports not currently in use causes a temporary power disruption and will throw your external hard drive off. In other words, you get the warning message that the drive was not properly disconnected. And as this can be bad for hard drives, be sure to properly eject your expansion & flash drives before turning off or on any of the ports and before adding or removing any connections.
