I received this 5 in 1 aluminum USB hub from Novoo. I own a Chromebook, and have found this hub to be extremely useful! It has 2 USB ports, a SD memory port and a SD card reader port. It is small and compact and easy to bring with you on the go! I love having the extra USB ports available on my laptop, because I normally have multiple devices plugged in. This hub is very handy to own, and I would definitely recommend it!
