I bought me the castle mainly because a report on TV that showed how easily most spiral locks to crack (there goes a forceps that paasst in your pocket). It is true that one or this padlock is not unaufbrechbar, but it is a lot more difficult and has a higher deterrent factor than smaller castles.
The technical features of the castle are cozy. the description, it includes facilitated consistently off and on, making a total of a stable impression. A mechanism prevents the removal of the key in the lock is open.
Conclusion: I am very happy with the product and can recommend without restriction based on the price in this class him.
