Bought this to go with my Abus frame lock, that is a great lock and it's always with you ~ I seleced the one where the key can be removed when unlocked. This cable (or the similar chain) make a great addition so your treasured bike can be secured to some (hopefully) imoveable object like a lampost. Well made with cutter resist strand design ~ not guaranteed but a great deterant.
I never leave my bike for long periods just the coffee shop or country pub stop.
I do have a "U" lock for those "left unattended for longer" stops and find the Abus Ugh brackets, while expensive, the best method I've found in 20 years to transport such a lock.
No I don't work for ABUS it's just I've found their products fit my needs.
