I needed something to sit on my main desk to fire midi notes into that could just sit there unobtrusivly, the other features are of little concern beyond the octave shift.
build quality is fine,usb cable was included, keys are small not great and the keyboard overall feels a little light but its only intended for a single purpose for me and in that sense its perfect.
I cannot stress enough how useful it is to get a very very small midi keyboard and AFAIK this is one of the (if not *the*) smallest out there.
