Basically, a blender is a free standing unit, that you add all your ingredients to and it pulverizes them to your required consistency. A handblender is a small appliance that you can use in the supplied beaker or in a suitable pan/bowl. Works particularly well with smaller quantities. You work the product yourself, capturing ingredients in each task. This particular model has a whisk for whipping small quantities and a mini chopper, again suitable for smaller quantities. This can easily be stored in a drawer if needed and is simple to wash. It really is personal preference that makes you choose one over the other.
