In total there are in addition to the continuous operation even three programs or three other functions. The first key is associated with the P. The letter P stands for the English word Pulse. The pulse function means that the mixer only while rotating, as the key is also pressed. It allows you to mix in short bursts or longer periods, the exact second as required. The key labeled CRUSH ICE is as the name suggests, for ice cubes. From ice can crush ice (crushed ice) are made. Crush ice is popular with cocktails. I do this crush ice in the summer like this in my smoothies. In the mode CRUSH ICE turns and pauses the mixer alternately. The last key is specially designed for smoothies. A short time is mixed here at the highest level what the device will bear.
I like the processing of the blender very good. Above all, the great pitcher, which is made of glass. Most Mixer namely have a pitcher plastic. Plastic jugs are quickly dull in the dishwasher, so my experience. Glass is less susceptible and looks after 10 washes still like new. I had the pitcher now about 10 times in the dishwasher and there is nothing to complain about.
The pitcher should be very firmly turned on the engine block. At first I thought my blender would be broken, because he did not want to start. Here, the glass jug had to be just a little harder turned on the engine block. Whether the pitcher is properly seated, you can tell by the two key symbols on the outside, which must be exactly to one another.
I use the blender for smoothies mainly, herbs, baby food and ice. To date, the knives have not been worn. The Mixer works just as good as the day without a visible reduction in performance.
What I lack is a pusher to push the fruit or vegetable from top to bottom. Instead, a spatula was settled that one but not as urgently needed as a food pusher.
Otherwise, the device is fixed on the countertop. It does not slip off abruptly when the mixing process is started.
A German manual is included in the package. Even this is not always self-evident.
Conclusion: The Klarstein Hercules convinced in processing and performance. He crushed even solid food in no time. For daily smoothies the blender is a better solution than this stick blender. All parts in the dishwasher up to the engine block. The glass jar is fine. Overall a great mixer!
