Good bits: For this size and portability it is just great synth. It sounds good and has good connectivity. Battery life about 4-6 hours. Plugged in charger does not make any hiss, buzz.
Bad bits: Sounds are quite similar with minor differences, no pitchbending. Quite a process to program sequences. Once one learns it its just a matter of pressing those buttons, but if not used for while, need to learn again.
