(This review was collected as part of a promotion.) My wife and I received the KitchenAid with the K5GB glass bowls as a wedding gift.  We have used it many, many times for various cooking projects and have thought to ourselves EVERY time, "It sure would be nice to have a shield for these bowls to keep ingredients from shooting out while mixing." Alas, KitchenAid does NOT make any shields that are compatible for this model of bowl.  Add in the additional weight of the glass bowl and it has created an equation for dissatisfied customers.
