Good light bike lock. I have been using this model for a while. My old one was unfortunately damaged by a bike breaker. But he couldn't open it. He tried it in three places without success. :) :) :) Probably with a cable cutter. He would have got through with a larger bolt cutter. However, only the plastic was damaged. This is what the lock looks like after it has been checked by a professional. Many thanks to the manufacturer for the good quality.
