I play with for 2 years.
What I like most: the minimum weight, dynamics and different sounds.
What I like least: Poor balance unites the different sounds right hand and left hand ADAPTS not very sound at the ball (I possde the model non-programmable orchestra, watch case yellow fa ade)
Price quality ratio expensive when compared with the new Roland.
I will take a light if I have to buy one, but I do not hide that I will try other brands.
The orchestra even when system is fairly gadget and not very fast handling. A crankset compliant twelve o'clock am welcome to drive or bundled mp3.
Liberty HF system is not at all reliable.
