"great for learning "
Verified Customer zZounds has verified that this reviewer made a purchase from us.
i started lessons as a child but never finished. so this piano is the one i recently purchased to learn as an adult and it's great. do not expect dynamics or sound quality of a real piano because this doesn't have that, but it is jam packed with a lot of features and is perfect for learning how to play.
