The steering lock must be thought of as a shared frisbee with a rod. The disc is opened and placed around the steering wheel, hooked rod, pushed closed lock, finished. The unlocking and remove also goes fast anymore: open with the key the lock, pull apart the two shared disk and lift it (which is sometimes a bit hakelig because the disc quite a bit has weight, but overall not a big problem - for ladies quite feasible) , Compared to the predecessor model, the upholstery seems to have improved, at least I still have not found any damage to the Lendkrad leather covering, as was occasionally complains. All metal parts are also carefully rounded so that is another reason why the steering wheel leather can not be slashed. The only downside of this product is that you have to find a place while driving it, because it is very bulky. This lies in the nature of things, because it was precisely designed so that it completely umschießt the steering wheel so that the steering wheel of evil thieves can not be cut, as will be made manifest at the steering wheel bar locks. I am absolutely convinced of the product and so far my car has not been stolen ;-)
