Query: A lemon but a great concept

I am about to return my 2nd non-working piano. It will not play in TV or piano modes and once on, will not turn off without being unplugged or batteries removed. The response from Fisher-Price was they were not aware of any problems with the toy and to send it in. My response: Let me know when it works and I'll get one then. The only reason I gave it TWO stars is because it's a great concept and when we tried it, my preschool aged kid loved it.Hope the rest of you have better luck.
