The lock is solid, heavy and well made, one would expect at a high security level and the price also. The installation of the bag on the bike is very simple and the processing is also excellent, as was the style. However, what bothers me is the cumbersome fastening of the lock of solid parts (mast, heating pipe or similar). Since I wanted to park my bike safely in a basement, I had to make me start on the search for a suitable attachment and which has already cost nerves. Slightly longer limbs would have been helpful here, then the amount would have been not so small. Getting used to is the closing mechanism, as it sometimes happens that the lock jammed. Despite everything, I hold this castle for very successful and can recommend it as the aforementioned negative lose points with a little practice, the "nerve factor" only. In my opinion, the number 1 among all bicycle locks, in terms of safety, handling some getting used to.
