The two holes were drilled quickly and even mounting the VESA mount worked without helping hands. The dowels, screws and a screw were a perfect fit. The model is very stable overall, the bolts are super tight - with some Grease optimally around the arm to be able to adjust well without a "self-perpetuating" to have. The arm can be pivoted both good, as well as tilt and tilt - the monitor held in the desired position even after repeated adjustment. Duration experience does not yet exist, but necessary to get to the screws nachzuziehenden ran well.
Accessories and even a carpenter's level are included. Since there is nothing to complain about, everything is right here.
Well, in hindsight he would still prefer me 20cm longer, but the model itself can not ;-).
