First, I would like to mention that this has Steckregal cost very little u. Thus, you can not expect high quality. The assembly is really simple. The plates are kept remarkably thin - pushes the price of course. The ground on which the shelf stands should be in balance, otherwise the chipboard shelves are (only 8 mm thick) do not fit properly and continuously from the wells of the plate rails (only 5 mm deep and 5 mm wide) to pop out the shelves with emphasis on making the shelf until stable. To attach the shelf to the wall (wall plugs) is really guessing. Had the shelves slightly thicker (about 12 mm) and have been the fold it in the longitudinal rails 11 x 11 mm, so I would call it recommended - but not so!
