I use it for almost a year. I confess his love piano sound, frankly it's the best I've heard (from rev below) for that price! J'value always a piano's bass and electronic mdiums (the highs are still pretty grnal), at least it does not squeaker squeaker, which is the case with other roland yamahah , brands that I dtest par excellence (well, for the piano). Kawai trs good brand, MODEL above is a little better at bass, but this does not justify a second the diffrence in price is double or more if my memory. Without state of me I say: better than its competitors in the same price, much better than many much more expensive MODELS. Only default: few gadgterie. But for those like me who do not care, who want to say it's a piano in their apartment because they can not put a true jump on it!
