Adjustment. Transitioning from electronic keyboard.
Overall, product quality was very good. After coming off of my first Casio electronic keyboard, the shift to an electric piano with real key field was not well explained in the advertisement. You really need to plunk down on these keys to get them to put out loud enough Musical tone. Maybe it is just an adjustment period for me. I am only playing three months and did not want to restrict my range any further on a 66 key piano. I just wish this particular product had a selection setting for electronic keyboard that mimic my Casio since people with arthritis cannot always hit the keys, hard enough on a standard, feel piano to make the note uniform with other notes. There is no shortage of other tones and sounds on this electronic piano. I just wish it had some that were actually usable.
