I did not like that the keys were only supported by a small piece of string on each side. Not only that, but there was about an inch of bare string exposed which looks ridiculous. I have tried to exchange it or get a refund but it has been difficult to do so far. I would also prefer 6 keys.I would buy this toy, even as it is, over a plastic toy any day though. I do not feel the need to deplete the worlds petroleum resources any further, or expose my child to petroleum products such as plastic.I think that wood is a million times better for building toys out of than is plastic. It lasts longer and is so much healthier. I saw the Wonderworld Eco-Friendly Neo Xylophone which looks like it might be better, although I have not seen it. I might try to exchange this toy for that one. Too bad it is only 5 keys too though.
