I have a KitchenAid mixer and only 1 bowl to use with it. I have to always wash the bowl several times during baking or cooking. Because I only have one bowl to use it with. Takes longer to bake when I have only one bowl to work with. 
Therefore, when I had the opportunity to try out this bowl (with a spout) I was beyond excited.  I love this bowl. Works great with my whisk attachment. Also is easy to clean, make sure you follow the 'care' instructions.  Pour spout is perfect and so useful with batter!  And it has a cover/lid.  Cannot say enough good things about this product.
