Quality is at the rendezvous! I do not regret having been offered this package that contains all diameters I need. The case even includes classic screwdriver bits (Phillips and Posidriv, star etc). Although everything 9.1 Kg, plastic is resistant and not sliding closure may open during transport. Used on seized bolts, bushings have not moved. And the lever arm arrangement allows for considerably more force.
A very good case that I will not hesitate to recommend, because it is the kind of material that keeps long!
