Well, what can I say ... Unwrapped, looked at closely. Attempts to adjust the length stop (as described in the manual): One has to gently squeezing the upper two "wings". Once cracked, then the length stop got a pass. A spare part would cost 2 (for a part what so 1-2 grams weighs). Thank you, no need, not in the product price. This part goes back.
I always wonder when something, whether it is aware of the company that they ruin their good name with such products ...
