I really wanted to like this lock, great design and very practical function. What I think would make the chain lock better is if it were a few links longer as well as making the locking mechanism on the padlock a little taller as well because when you're locking the bike up the material that wraps the chain gets in the way of the pad lock and gets stuck or is unable to reach. Also I feel like the padlock should be simpler, you shouldn't have to keep the key inserted to lock/unlock the Pad it should just click in smooth so you can go. It's also uncomfortable when people start to stare thinking you're trying to steal a bike but really you're struggling with your own lock..lol Still need to get use to this chain I guess but still feel like the design could be improved. Good for a commuter but if you work as a Courier I'd advise to use a different chain that's quick. P.s. .. I work as a bike messenger in NYC... Thank you.
