Review: Durable, but small. Security options limited. - Cool and sturdy little lock. Useful for locking your tire rims to the frame. This is a great lock, but if you do not have access to bicycle racks or thinner poles, I would suggest that you purchase a larger lock. This one is very small and may pose a problem with those who live in cities where locking options are sparse or bicycle unfriendly.
Review: bought 4 years ago STILL GOING STRONG - I bought one of these in may 2020 to use along with another small Krypnonite mini on a beater bike in NYC. I dont leave my bike out at night bcz thats a big NO NO here in the city, but ive left it locked up for most of the day at times & this one worked perfectly as an additional security. My beater recently died (RIP my friend) & I now have a somewhat nicer bike with more expensive components on it so Im upgrading my locking game however I will still also use this lock which is STILL functioning perfectly -I never had an issue with it, at this point the rubber coating is tearing off in the u area but other than that is still going strong. Id definitely recommend as an extra backup lock.
