Series Error chuck

Was first with the drill very satisfied (good price, performance excellent stamina of the batteries almost unbelievable and MacPac also ok). However, the first screwdriver after 4 weeks already the chuck or bearing defective, so the wrench even when screws of 5x50 screws to "eggs" began.
Delivered easily a replacement unit via Amazon get (great service by AMAZON !!, but the new screwdrivers same problem after two weeks (= 1 pack 5x50 screwed and 500 bolts unscrewed). All those buyers who selbes device in use, should check their screwdrivers once (after unpacking there was absolutely no play at the chuck, after two weeks it was 1mm in every direction). Further recessions 459 series confirm the problems encountered with the drill chuck.
Send now also the second wrench back and climb on the model DDF480RMJ order.
