Customer Return reason: Item arrived damaged - I think because of insufficient packaging material. The housing of the rotor motor has a crack and was not in place anymore. The plastic part of the rotating mechanism has therefore been completely damaged: cogwheel, spring, bearing ball, screw and pieces of plastic were all to be found inside that plastic bag covering the main part of the fan. I need a working fan now and therefore opt for the refund option (instead of replacement). Thank you.
