For a keyboard without weighted keys, it is surprisingly responsive, and the tone is good. i took it last weekend to play for a funeral, and it was easy to transport, didn't require extra speakers, and surpassed my expectations. it is supposedly a "beginner's piano", but I am a career pianist and no longer use my Roland at all, because it has three broken keys and is too heavy to take for repairs. This Donner held up to all my practicing for a theater production, and is still going strong. i probably won't even get my $3000 Roland MP300 fixed, at this point.
i highly recommend! i have used the transpose feature several times to adjust the pitch, and the music holder is big and sturdy enough that my music book doesn't fall forward every time and turn a page, as was the case with the more expensive Donner the theater troupe bought.
