The unit I have not purchased through Amazon but directly through the Klarstein site, so I will not make any comment about Amazon itself. The unit had cost me 119,90 euro, in blue, incl. A coupon code via 10.- of Klarstein to register for the newsletter. Can make and set off on the shopping at Klarstein each. After long and intensive research, I have decided for this mixer and am very satisfied. The unit "broken" everything you would normally do in a blender, but surely, other materials such as wood, hard plastics, etc. I have not tried it, but the power delivery suggests. And who wants to give other than food in a blender? The green smoothies, for I have bought myself, prepares the Herakles 3G without problems and in a very fine consistency. Even the seeds of lemons, oranges, apples and even a whole avocado core were without, "grind" large pieces and noticeable residue. Use z.Zt. frozen for my G.Smoothies, such as spinach, kale, broccoli, etc. these are processed without much "effort" of the 6 blades. Some recessions I read that it had only 4 blades, but there are 6, I can confirm !! 4 up and 2 down "kinked". Decided I am also this model because it provides a manual control of the rotation and pulse function, for flexi use (grind from coarse to fine, rather chop etc.). Because I have the device since about 1.5 weeks, I can not say much about the longevity. But ... The appliance does not heat up, even at 50-60-80 seconds continuous operation. It does not smell when it is in operation. It is a bit noisy but not louder than other large Küchenmascinen, for example. our little mixer of Mr.Magic similar loud !! After all, a "Big Block Machine" 1500 Watt is in the Heracles there !!! and have it in them .... Also impressive is the size (with container about half a meter !!) and the weight (just under five kilograms), also here you realize that it is a professional high-performance mixer. So if anyone is looking for a high-performance mixer with reliable use and a favorable price / performance ratio is absolutely right here. There are also other brands and suppliers for 400.- and even to 2200.- !? but what can be better .... ???
