The key, especially from size 4 are there for two years now in use and fulfill their duties, despite some not quite correctly handled excellently.
The key sizes from 7 are often misused by the use of lever tools and this has so far survived without sequelae.
The storage in the very stable plastic version is not optimal, but to save space, so that the tool is likely to find its place in any standard workshop trolley. The exit of each key is not perfectly solved, because you, as already repeatedly described herein, the other key must rotate by 90 °, but since this is still faster by hand than seek out others from the otherwise usual roles Manufacturer I see no reason for a point deduction.
Who relies on durable tool and will not be satisfied with the labile DIY tool is with these Allen keys, have his joy. After all, the manufacturer itself is convinced of its quality and gives 20-year guarantee.
