I compared this to the KitchenAide hand mixer I have, and honestly, they are both very comparable. The attachment tools in the Braun were slightly bigger and they come in a nice bag to keep them in. 
I used it to make some whipped cream and it took about the same amount of time as the KitchenAide and was as loud as the KitchenAide.
I’ll definitely be using this in my baking, especially since I have kids that like to help. No more arguing.
