The castle is ok. Bought it for a cellar door and it does the job. Setting the combination was easy. Be careful not to twist the supply origin combination can happen quickly. The Guebel goes but only minimally to the castle. One seems almost to have it not pressed. Respect. Security I'm a bit skeptical. At sensitive places I would therefore rather not use. But who used as even a combination lock. Etc. For provisiorisches shutting of doors, lockers but certainly suitable.
