It has USB 3.0 and 4 ports, for a low price, The Warehouse has their own brand version priced a bit more, when it doesn't even include USB 3.0. Very happy with my purchase, as I can now run a mouse, Wacom pad, and USB flash drives simultaneously from my Chromebook. Have used for a week or so now, and so far, no drawbacks at all. Would recommend to other potential buyers.
