I used to work in a restaurant and all of our blenders were waring. We sold numerous milkshakes and frozen drinks. I always wanted a waring because they worked so well day in and day out. I have not been disappointed, not once. I use it for EVERYTHING that can be put into a blender. It is a rock star. Durability HAd an issue with a blade breaking but it came from william sonoma so they replaced it. That was several years ago and haven't had an issue since.
