My review refers to the previous model KB720, which has been replaced by this model KB790T. The mixer has a very robust, the level of craftsmanship is good. The upper half of the body is made of stainless steel, the bottom made of plastic. The control panel is integrated into the stainless steel surface and consists of soft-touch pushbuttons. This makes the whole impervious to water and Co. Thus, it can be cleaned prima moist. The jug is made of solid glass, which it shows the weight of 1.9kg incl. Knife and cover. The blades are made of stainless steel. The model KB720 has 4 smooth crushing blade, the model already KB790T 3 knife with sawtooth cut and 3 Smooth, which again should have a positive impact on the reduction itself. The 1100W motor examined in the consumer class has no equal. Mir is currently no known consumer device that provides this power. The intelligent motor control (motor protection) of the motor (Slow, 1,2,3,4) runs in each Mixstufe slowly and increases to the corresponding stage power. Unfortunately, the model KB720 can not umbedingt of Silence of the question, because the mixer is quite present to work. After all, even quieter than many Mixer 08/15. The Mixleistung is already very well for the model KB720. Ingredients are crushed quickly and effortlessly. One can z.Bsp. super Smoothis manufacture. The mixer also offers a vario / Pulse and crushed ice function. The latter, however, be treated with caution, because the ice is crushed so noisy that you need earmuffs. The result ... well. The special feature is the Vario-pulse function, with which each can Mixstufe pulses. All parts (except the engine block and knife) are dishwasher safe, but can be cleaned due to the simple disassembly prima hand in the sink. Krups also granted a generous warranty of 5 years on the motor. On the whole, the KB720 or current KB790T is a very good consumer blender. The price / performance ratio was right in this case anyway. I would buy the blender again.
