when I purchased this months ago I was looking for a cheap usb keyboard

The only downside is that the USB is a bit loose so you have to make sure you keep it still so that it doesn't unplug, but this is worth getting if you use MIDI often.

It uses a proprietary USB which is very flimsy at its input into the unit

Also the user reviews here have a ton of complaints about a faulty usb connector, but seems rock solid to me

The problem exists with the faulty usb connection which eventually stops connecting(I read the reviews mentioning this but didn't think it would happen to me)

Love the USB in lieu of MIDI hook ups.

USB Mini-B port is frustrating and weak, and doesn't work from time to time

Great little (very small) usb keyboard
