- The suitcase is very durable and thought out to the smallest detail.
- Metal alloy of heads and extensions, as if there is not enough heat treatment. I changed the wheel (with a hand crank) on a car and, after unscrewing the wheel bolts, I saw jams on the head and extension on all four sides. The keys in the set are very small (metal savings), the Chinese ermak is more convenient and just as convenient even for the pros of the wurth key.
