The castle is nice and easy, but acts in the works not so solid work such as a brass lock. For quick entrainment fuse certainly usable. For safety reasons: I have the Vorrezensenten comparable locks from Abus regarding Knackbarkeit only "distrusts" (for combination locks are usually with flair and possibly hearing to crack), and ordered the castle itself.. However, this version actually something much play, so you can feel the code with a slight train at the temple and turning the series of numbers from the bottom up sometimes (!): With each correct number the strap loosens something to the whole after 30Sek.- 2min. is open. But sometimes that does not work across multiple attempts, because the lock blocked. I am somewhat at a loss to the effect and have separated myself as a precaution from the castle. Of course, a potential thief would have to know about the possibly weak point. Therefore, as a deterrent (which may often suffice) quite usable. But I have far more secure combination locks this design in use, where you can still hear something neither feel. Unfortunately, from a Finnish construction market ...
