I have had this ice cream attachment for 5 years and I use it 2-3 times a year.  When not in use, I store it very carefully in it's original packaging, in a safe location.  This week I put the bowl in the freezer to prepare to make a batch of ice cream and blue liquid has leaked out all over the bowl and my freezer.  I can't tell where the leak is on the bowl and I do not feel comfortable using it to make ice cream.  I loved this product until it self-destructed.  Really a shame for such an expensive item.
