I have the Mr. Magic for one year in use and use it daily. After about 3 months my first knife unit is broken. The rubber block down the hooks to the engine and the blade unit rotates is, apparently, more and more frayed over time. The second blade unit is half a year later died the same death. The cleaning is poor, because you have to ordinary cleaning herausprökeln the sealing rings (with a knife or something). The sealing rings are not in the dishwasher (eg when the lid of a container in the dishwasher does), because there they wear out in the hot water and then leak. In my blade units, the sealing ring, despite proper insertion frequently not dense and the sauce is drizzled into the engine block. The device is in ice cubes very loud (louder than usual).
Nevertheless, I have to say that the device has served for its price, and my friend both work blade units still (also for about a year in daily use). We must for the price but just do not expect the device lives forever.
I will now still buy me a better device, I'll continue to mix daily smoothies so.
