Pros
Pro For low-risk situations
This u-lock can work well in low-risk situations, or as a secondary lock to secure your wheels or seat.
Pro Keeps wheels safe
There is an included cable with the U Lock, that allows you to secure the other bike wheel (not locked with the U Lock itself), or the seat. This is great for city riders who have quick release wheels, as an unlocked wheel makes for easy theft.
Pro Relatively easy to transport
There is an included mount for the U Lock, which allows for one to easily transport the lock with the bike with no further equipment needed.
Pro Good for lower risk situations
The chains on this lock are 9mm in diameter, which makes it good for only quick stops in busy urban areas. Chains under 13mm can still be cut with bolt cutters, which isn't good enough for higher-risk settings.
Pro Easy to wrap around objects
This Kryptonite chain has the flexibility of a cable lock. Even at the mini size, it will still be able to wrap around more objects than any u-lock.
Cons
Con Can be cut with the biggest bolt cutters
Do not expect this lock to protect your bike in high risk situations (leaving your bike where there's a crowd, especially if your bike attracts thieves attention). The tubes 13mm diameter is not invincible against bolt cutters.
Con The lock might freeze
Be careful about using this lock in winter conditions. There are some users who report the key-hole freezing shut.
Con Heavier than u-locks
At 9mm diameter and 21.5" length this is not nearly the heaviest chain around, but it's noticeably heavier than most u-locks.
