The structure is slightly out of hand. It is a short cross-screwdriver is even included.
I have left out the small piece of wood (bottom front center) - so fit in the lower compartment still comfortably in 2-3 A4 ring binders.
Two stars deduction there that the height adjustment is not very reliably: Although can be pulled out of the upper table, so you can use it while standing. However, the supplied plastic holders with the associated rotary screw, which should fix the table at the height position, very weak. If a little more pressure on the plate exerts (eg if you use a paper punch on the plate), they slide down. (For a stable solution, I would have spent even five euros more.)
