I have never made homemade ice cream before, so my only comparison is store bought.  And holy cow, is the homemade so much better.  I followed the simple recipe given on the directions with the ice cream attachment and it was so creamy and delicious.  The attachments are easy to use and clean.  The directions are very clear and easy to understand.
On the other hand, the bowl must be frozen for at least 16 hours before use, so it will require planning.  I also wish that KitchnAid provided a couple more recipes besides vanilla.  
Overall, this is an awesome product and I plan on making two batches of vanilla ice cream to go with my apple pie for Christmas.
