This is a brilliant lock. It feels very strong, and it is quite small and compact so it fits in my bag without problems, and around my bike without any issues either.
I'm unsure what to make of the bright orange colouring though, it can make it stand out when your bike is locked up somewhere which may suggest you have a valuable bike, but I'm not sure.
When locking your bike, remember to loop the cable around the rear wheel and into itself (as it explains in the instructions) as I originally discarded them without looking and couldn't figure out an easy way to secure both wheels and frame until I got laughed at for the unorthodox method I found. It will make your life easier!
