The fast start feature of the SmartPro Hand Blender Model 313 ensures that you get to work right away, with no delays. As soon as you press the power button, the blender kicks into action, reaching full speed immediately. This is especially useful when you need to blend something quickly or when you’re multitasking in the kitchen. The quick response time means you can get your blending tasks done in less time, without waiting for the motor to build up speed.
