An original Kensington lock is better processed and is also correct (finally) in the castle of the notebook. This castle is noticeably less well finished, making inter alia the joint at the end of the rope or on too long geratenen locking mechanism noticeable. The castle hangs by "loose" in the notebook. "Smaller Belanstungstests" but suggest that the castle perfectly fulfills its purpose and a notebook (or similar) to protect against theft. Who wants to buy a lock to secure a device and for the enormous price advantage takes the poor workmanship in buying, would not hesitate to resort to this castle!
