I had the earlier version the 350. After a short time the keys started making a audible thump and not a realistic hammer feel or sound. I don't know if they've upgraded the keyboards. I spent a short time on one of the newer home models and and Styles are OK for home entertainment but not suitable for a professional arranger.
They are a good value for what they are.
