Drawers assembly no problem. Rails mounted on the side panels (screw) - no problem. Then the ground came and here the manufacturer has not been paying attention. Here the holes have been swapped on each side so that they do not match the holes in the side panels. Where the big hole is part of a small hole, and vice versa - where the small is the great part back. Then it would have been right.
As I prepared both roll containers for assembly, I can not send them back. So I have set 97.56 euros in the sand. In addition, now the garbage costs of 10 euros for the disposal.
The one star I give for the fast delivery and can only advise everyone else to stay away from these trolleys. Amazon carries these products through any quality control and sends it in the original package. Thus, the manufacturer of roll containers also gets money for its production errors - also saves disposal costs for it ... and the end user and Amazon customer is ultimately the loser.
