The mixing bowl that came with my KitchenAid would not come out of the mixer one day and we had to extricate it, and it didn't survive too well.  Apparently, this is a common issue with some of these bowls, and depending upon in which they are made, it may be more likely than not that this will happen to you.  I read many, many reviews in an attempt to locate one that would not cause this issue again, and I'm happy to report that this bowl works better than the original bowl that came with the mixer.  It is a quality, heavy metal bowl that fits properly in the mixer.  If you need a replacement bowl, this one works, so snap it up!
