I bought this to use while the "Blade" charger is plugged in. Basically, I bought it for USB connections. It works great with everything I have plugged in (external mice, flash drives, external hard drives). The USB port in blue is a USB 3 port, the other is USB 2. Feels very cheap for the price but so far it does what I need. I would have preferred the HDMI output to the second micro SD slot, but that's a minor complaint. 5 stars because I knew it didn't have it when I ordered and the fact that everything about it works as it should.
