NOTE: I'm reviewing the USB 2.0 unit with 4 ports, not the USB 3.0 unit with 3 ports.
This is a very small, lightweight, and very portable USB 2.0 hub that can come in quite handy. It's great for connecting to something like the side of a notebook or other device where you need a few extra USB 2.0 ports. There are no cables or cords on the hub to get in your way and it can rotate 180 degrees.
A couple notes about this hub: there's no external power connector to supply extra power so don't plug in power-hungry devices. Things like mice and keyboards should work great. Also, it's only USB 2.0 so if you need USB 3.0 speed, then you'll want something else (like the USB 3.0 unit which is now an option but has only 3 ports instead of 4).
It's also quite cheap. I can't find anything to complain about. It does what it's suppose to do very well and at a good price so 5 stars.
NOTE: I was sent a free product sample for review.
