I bought an Artisan Design Series mixer with the glass bowl less than a year ago.  I have only used it about once a month.  While my husband was cleaning it, the edge of the bowl barely tapped the side of the counter and it cracked almost all the way around the bottom.  It is not cracked through, but I am scared to use it and have it shatter.  I am incredibly disappointed in this product and frustrated that I have to purchase a new bowl.  Save your money and get the stainless steel bowl.
