In addition, both the Allen screws and the hole itself is not exactly: when the respective two segments do not exactly one above the other in the original, leave the parts not close, or slide the screws incorrect in the bore and the segments fall auseinander.zudem again arise always make unequal / uneven, the high risk of injury bergen.dafür I have no verwendung.eine assembly is circumstances under "adverse" .the not lead to success without pain Allen screws can be already at the table reluctantly mount, and not always grab korrekt.dies's Committee on mich.eine return is only with the offer of an exchange against as badly made staple from the hands of apprentices First year gekontert.somit remains the buyer on the damage and the retourekosten sitzen.bei me these are 70 euro alone for the two stretcher, thanks! no star I could not forgive.
