My 3 year old loves this piano! It is so fun and the microphone is a great bonus! Lots of musical options to use when playing with this adorable piano!
positive

Just opened my plastic package because hard to see if center pin was copper as pictured in ad.. sadly it was not. By the way, do not tear open your package because it states on the package,"No returns if bag is open" what a waste, I should have just driven to an autoparts store.

put on my car back window and noticed corners and edges did not stay down too well. did not think too much about it looked at sticker a day ago and looks as if water penetrated under sticker and discolored it. had to take it off looks terrible. guess it supposed to be on a bumper or window that does not get wet.....
