The Cuisinart Evolution Cordless Hand blender is wonderful and is replacing my corded immersion blender. I think I will use the cordless blender much more than my old one simply because I won’t have to plug it in and it is so much easier to clean after use. The battery lasts long enough that after a full charge I will have at least 3-4 uses before it needs charging again. I was a little concerned that it would not be as powerful as a corded model but it is strong! Easily pulverized fresh jalapenos for a salad dressing and handled very thick milk shakes. And easy whipped cream with the whisk attachment! I am looking forward to being able to blend hot soups to smoothen them out. 
One of the best things about this hand blender over corded version is that it breaks down which will enable easier cleaning. While the attachments are not dishwasher safe, the smaller pieces are easy to clean by hand. Great improvement over my corded model!
