The castle has six months to work. after that it was no longer in spite of correctly adjusted number. Hours of fumbling avail. I have used the castle as a padlock for the cellar door, but could not come in my basement. I remained only to appoint a bolt cutter, which can crack this castle. In hösten tones praised and what remains is the anger and disappointment of a relatively expensive brand lock. From me it gets no recommendation. Addendum: I sent the cracked up to ABUS lock and have it get a free replacement lock. A fair gesture of ABUS thanks. Hope that this will last longer.
