I ordered this product sight unseen and 100% based on the positive reviews on Amazon. When I received this product, both my wife and I were pleasantly surprised how good it looked and how well it was made. No sharp corners and very bright colors. My 9-month old baby girl took to it immediately.When I was examining the pieces, I found one cube had a crack and I can see how it could come off if my kid kept chewing on it. I hope this is just an aberration and Haba does better QC overall. I am going to return this and order another. Good thing Amazon has free returns. I will update once I get a replacement.
