The unit has 450 watts and has two S-meter. Most devices of this class have only one knife. As a result of these Ausstattungg you get just about anything small. Buckwheat, cashews, walnuts - no problem. Also you can certainly times crush 15 seconds at a time in order to achieve a very fine consistency, without the motor breaks down. (There are devices where you will shred a maximum of 10 seconds at a time ...) The unit consists of only 5 parts, the container, the blade (which consists of two parts), the lid and the engine block. It is dishwasher safe up to the engine block and the mating is quite easily. Full Punktuzahl from me.
