Device makes a high impression-and mixes actually very good when it is running as. Bought two units, since we have two kitchens equipped. The units were operating normally and after 1 month, the first one was defective. Complicated return procedure to Clatronic (sells Proficook). 3 weeks waiting for the return. After the device was repaired was also the second mixer from the same obvious defect. The repaired unit then held exactly 2 weeks. now have 2 Defective devices in the cabinet and also a mixing bowl to which a nose is already broken and the vessel will no longer fits on the device. "Professional" is this mixer only break ... Save yourself trouble ... Buy another device
