I have tried the set today for the first time and used to express the bracelet pins 3 of the pusher. All 3 (incl. The blue Ausdrückers) broke after low pressure immediately and are now no longer be used. The bracelet course I did not get shortened and will now take it to the watchmaker. Whether the Uhrendeckelöffner of similar poor quality I have not yet tested. I would not buy me the set again and by buying only strongly advise against. The 10 are better invested in watchmaking.
Update 03.02.2013: Today I wanted to try the opener for pressed lid. But I had no chance to open the lid so.
