Really hard to recommend using a cable lock for anything --- In your situation I would still probably invest in a ~$50 ULock -- the kryptonite mini 7 is pretty solid and not that heavy. Best practice is to have an appropriate ratio of quality of lock to quality of bike...so like a fancy lock for a fancy bike. The issue is that a thin cable lock is basically like having a denominator of zero. It should be malpractice to sell those things.
