Bests & Worsts Reviews from Amazon

I purchased this lock with very specific use cases in mind. I have a big, study u-lock, which I find heavy and hard to carry. It is also not necessary for everywhere I go - if all I need to do is a quick stop, it doesn't require a monster of a lock. With this new lock I wanted something versatile and convenient, for when I needed to leave the bike unattended in a busy area. Not looking for the highest form of security available, but rather something easy to keep on me at all times, lock and unlock. This Sigtuna folding lock fits the bill exactly. It isn't excessively heavy at < 2lbs, while feeling sturdy. It has this flexibility quality to it, allowing you to lock to virtually anywhere. The length is appropriate - longer than my u-lock, but not too long. The joints are very smooth, it's very easy to unfold and fold this lock. Contrary to some reviews, I didn't find any resistance in inserting or rotating the key - it feels very easy - maybe this has been improved. My favorite aspect of this lock, however, is how compact it folds and sits on the bike. Mine is mounted to the bottle mount and it stays absolutely still, no rattling, no noise. I am interested to know how it will hold over time, but I'm happy there is a warranty.
