If you want a best blender mainly for making smoothies and frozen drinks, choose one with at least 500 watts of power and an ice-crushing blade. Ice-crushing blenders are available in full-size models or lower-powered personal blenders. For chopping/grinding tasks, you'll need one with a chopping blade and processing functions, otherwise a standard blender will usually be adequate for most blending, pureeing, stirring and mixing tasks, such as making baby food or creaming soups. more
