I got this one to replace my old hand blender. This guy has a small food processor and whisk attachments, too, and they greatly complement my 13-cup KA Architect food processor and 6-qt Pro mixer. 
The hand blender is a must whether you have a baby trying their first solids, a toddler loving his veggie dices for finger food, a K-er requiring daily school snacks, a whole family fond of pureed soups for winter suppers, or - like I - all of the above.
I did find plastic to feel less solid than in my older model, and call me a retrograde, by the whole installation and clicking-in of the attachments to the motor hand worked easier and felt more reliable there, too. But I shall just keep my hopes high, as all of my KA appliances have always proofed  to be reliable. [This review was collected as part of a promotion.]
