    Damaged delivered. Now perfect after repair.
    I heard " ups!!!!" . before I had my shoes on and opened the door the driver dropped it at another apartment. In less then 30 seconds!!!. Then I checked the box. Damaged outside. Styrofoam damaged inside. Pump itself damaged and loud. Is it only a b or c grade product or did they sell me a used one as a new??? Who knows. But I know , next time it is not worth to spend more money for the name. I would never buy a pump with name on, twice the price of a china product , only to receive less then Chinese quality.UpdateRepaired myself .A scratching fan blade was the origin of the noise. Now it is silent as a pump should be. Amazon compensated my work. Good for 4 stars now.New update after month of use:Daily use has no negative impact. Vacuum still 5 mbar better as specification, fast,reliable , low noise.
