The unpacking and setup are simple and understandable. A quick rinse of the mix jar is enough to put the device into operation. The design is a real eye-catcher. Pleasant, though difficult, is the mix of thick glass jug. It can be quickly detached from the base and very clean. Again, the dismantling and re-back is easy. The pitcher even fits into a compartment of my refrigerator door. Thus, the content does not necessarily have to be transferred to another vessel. That is practical! The device is very stable during operation, but is quite noisy. I've used it for shredding raw carrots and oranges, everything was minced after three minutes and as drinkable smoothie. One drawback I find the tapered shape by control knob, so adjusting the working levels. I have no good grip to operate around the hard to moving button. MIX pitcher you have to work during the hold, he has no way it engages. A child safety does not exist. I am very satisfied to the button, the missing child safety and well inevitable volume. Therefore four star.
