The Bamix is handbuilt in Switzerland to last. Each unit is tested many times during production to ensure precise performance. With 2 speeds and 3 stainless steel blades that are easy to change, this hand blender is versatile enough to do countless kitchen tasks. The aerating blade is set at a slight angle for optimum performance to whip or beat liquids, even turning skim milk into a whipped topping. The blending blade mixes, purees, and emulsifies thick or creamy mixtures so you can make homemade mayonnaise in seconds.
