(This review was collected as part of a promotion.) I have had this glass bowl for about a year now.  I had just made some cookies and hand washed the bowl and set it down to dry on a t-towel on my counter.  I then put another bowl down next to it and it must have hit the glass bowl just right because it made a sound and I noticed a huge chip on the rim.  :(  I love my KitchenAid Mixer and use it almost every weekend for baking but I was disappointed that such a minor tap from another bowl [from one of my vintage - 50 year old FireKing jadite bowls] could do the type of damage it did.
