As much as I hate to repeat myself I posted a review of the Juiced 10-port hub in another thread( https://bitcointalk.org/index.php?topic=263577.msg2824064#msg2824064) so I'll paste it here:
-------
I bought the Juiced 10-port from Amazon and suggest getting something else.  It'll run 8 erupters but when you plug in a 9th it starts to lose contact with one, then another, then another and the only way to fix that is either restart cgminer or unplug/replug the miner.  The Anker's extra amp makes a big difference.

Adding insult to injury my Raspberry Pi can't see this hub at all, so I think I'm going to order the Anker from Amazon and return this one.
