I just installed this mill, identical to that of its competitor Wiltec just let me go after 8 months. The SAV (seller located in Germany as well) must be of the same level, ie nonexistent: unlike ours which engage the repair / replacement for at least one year in the case of German there no guarantee, I quote. "We inform you that there is no one-year warranty period Any liability for the absence of assured quality is only applied if the product already has a hidden defect at the time the the seller delivers to the buyer. Several defects are not covered by the responsibility for the absence of assured quality, such as when the product loses its use for the intended purpose due to normal wear and tear. " Clearly, if after 7 months the unit starts to purr while the pump but not evacuated, and repeatedly after the many disassembly, cleaning etc required by the service, you just have to in buy another one, hoping it would last longer (otherwise it quickly becomes more expensive and certainly more difficult to maintain that the French device which costs in the base model, three times more expensive).
