Step above a childs toy

Comments about Casio CTK-2100 61-Key Portable Piano:

This is truly a 'beginner' keyboard. You get what you should expect for a low dollar toy.I think this is a poor choice even for a beginner starting out-the quality of sound and performance is very poor and would be a discouraging start for anyone interested in learning the piano.It doesn't even come with the adapter cord- you have to order it separately or else run it on batteries like an over-sized toy. Which is pretty much all it is which is why im giving the one that was given to me to my 3 year old to play with.
