“I have owned this lock for 6 years and still use it daily. Never had an issue with bike theft since I bought it, and I leave my bike in a city centre all day where there is frequent bike theft. Size of the chain means you can secure wheel as well as bike frame, and you can lock to basically anything. Can be worn on waist but also cross body. Getting a new one now because I lost all my spare keys. Will probably never bother with a different brand.”
