It’s hard to assemble properly—the bottom of the blender leaked my protein shake all over until I screwed it on tighter. The blades don’t pulverize frozen bananas well enough on any setting, so I’m always left with lumps on the shake, or the motor isn’t powerful enough to drive the blades. My cheap plastic Oster blender went through frozen fruit in a shake perfectly. There’s something lacking with this Cuisinart blender. Haven’t tried the food processor yet. Not having great expectations, but I like the way the combo set looks. Good concept, duo containers, just poor performance.
