Cable looks good. Length allows to connect front wheel, seat, rear wheel to the U-lock. Flexible enough to fold 2 times in circe and put in backpack. Used in +5 C for 15 mins. Dont know what happens in winter during - 20 C degrees, I estimate that metal wire will get very stiff, because my previous thin wire did that in winter when I left it outside for 2-3 hours.
For stress tests, check articles on google or youtube. Havent tested myself, nor tested by burglars (I hope never will).
This is a very sturdy 10mm thick high tensile security cable from a trusted brand. The 2m length offers plenty of options for providing additional supplementary security to your main lock. This cable is the non recoil type which means you don't have to fight any spring action when threading the cable through the desired items. At the time I purchased it was on offer at £12.21 with free delivery which represents excellent value for money.
