Meanwhile, I was accompanied by this lock every year and I would highly recommend it. The lock cylinder is sure, making wise even in snow and rain no problem, at the beginning but once I oiled him since he was a little stiff. The plastic tube to the actual chain does not only visually what her but leaves the castle still a number appear larger and is very stable. Unfortunately, it is in the long run not so friendly paint, as I thought. When normal connection no scratches are still formed, I transport it but wrapped around the handlebar (the saddle it bothers me) and the shiny black paint has started to angemattet by many small scratches. Unfortunately, the locking mechanism is not protected from ice spray, which is found only in higher price and weight classes. The weight is given the stability fully in order, even though I had to get used to it.
