I was given this as a wedding gift less than 2 years ago. We didn't use it for a while because it was so big. A few months ago I was using it (for the 3rd time in it's life) and a huge crack went down the side and a chunk came out, throwing tiny shards of glass everywhere, including my made-from-scratch bread dough. I was using the rubber-like mixing attachment, so it definitely didn't hit anything and nothing touched or scraped the bowl. I was so excited about this bowl because you can't make dough in a metal bowl, but I don't think I'll be buying another of these bowls.
