The ABUS 201/70 has certainly not perfect protection against professionals and was it never developed, but against thieves of opportunity and "jokers" it certainly helps.
With a pocket knife or scissors, the cable can not be solved and the probability that someone has a side cutter in his pocket, then probably rather low (and even if it has the thieves then safely apart not only on a helmet or seat with seat tube ).
To access the code, can be chosen freely (3 digits) and the attitude towards it is very easy.
Without pressing the Arretierungsknopfes, the steel cable can not currently move back.
Once the lock is in action (rope "latched") and the combination was adjusted, both the button for locking rope, and the button lock to unlock. When the right code is set, you can open and only when it is open, you can also solve the rope-locking the lock.
The cable itself is surrounded by a plastic sheath, so that the risk of any scratches was reduced to a minimum.
Another type of use, which we later remembered: On vacation.
The fact that the castle is so small and compact (approx: 50g, 8cm x 5.5cm x 2cm), it also fits into any baggage and can thus go back up the suitcase somewhere fast times or on outings, when his backpack times must leave behind.
Conclusion:
A smaller and more effective protection against the fast access. For security reasons, but you have to resort to other means. For the purpose, where this castle was conceived, but perfect and recommended.
