B.O.,
I think you know that I am not looking for advice on what to do from now on. So please spare me the lecture. It wouldn't have mattered if I used a heavy chain instead of a cable. The faulty U-lock was a sitting duck. The person who should be worried about what is possible is the manufacturer. They shouldn't have let the retailer continue to sell this product. You've made your point and it's superfluous. Cheers.
