Query: Don't buy, bad quality

i ordered two, they BOTh came with keys broken off already. i tried to be positive about it and blame it on the shipping, but within the first use several other keys broke of and by now the xylos are kind of a mess. what happens is the little rubber peg that pokes through the chime bar to hold it on, is so incredibly cheap that it breaks off and you can't glue or fix that sort of thing. terrible waste of money. There is another brand that has all the keys screwed on, I wish I had gotten more of those instead.
