“This is a good hub which (unlike a similar one on Amazon) comes with a 2 Amp power supply. But care is needed as this hub feeds back power to the Pi. This means it will "fight" with the Pi's own 5V rail, which is not good for the Pi or its power supply. If, like me, you have a model B without USB polyfuses, this is actually quite handy as the Pi needn't have a separate supply at all. But if you have polyfuses I wouldn't recommend this.”
“Cracking good little USB hub. I hook it up with my keyboard, mouse , wireless dongle and a webcam - then I discover. It also power up the Raspberry Pi as well (no need for another power cable) bonus and highly recommended.”
“According its size I think it's ideal because you don't need a big space to put it there, is small and ideal not only for Raspberry but for other devices such us PC, etc.”
“Got this hub for my Raspberry Pi, and I highly recommend it. No trouble powering the Pi and a Logitech webcam that the Pi couldn't power by itself. It's been on for days and no troubles. Does what it should.”
