Query: Huge Disappointment

As with the other reviewers, Santa delivered this toy for our 2 1/2 year old son. He was soooooo excited. Unfortunately,we first of all could not get the screws out of guitar to put the batteries in and then when we finally did get the batteries in, it does not work. When I tried to exchange it at Toys R Us, they are of course out of stock. There was a shopping cart behind the return counter at Toys R Us with 4 more of these that had been returned becuase they do not work. My son was soooooo disappointed. Shame on the toy companies for making such a faulty product that seems to have disappointed little children everywhere on Christmas morning. The company that manufactured this toy needs should be held accountable and make restitution.
