This keyboard has a very good build quality and does exactly what I needed of it. I use it simply as a midi controller to control synths in my DAW and it's great. Considering its affordable price it also has some good features including a pitch changing joystick and octave changer plus other features I'm yet to use.
It also came with some useful looking software, including EZ drummer Lite, although I already have the full version. If you require a small keyboard that has some useful functions and is well made this is one to consider.
The only other thing is that it's USB powered, so if you only want to use the midi output you'll still have to also connect the USB to something.
