1. AMAZING!
I have bought a few different types of chain tools, this one is by far the easiest and best! Easy to use strong quality craftsmanship. I have used it 6 time on my person bikes and never had an issue. It can be a bit unnerving changing your own chain especially getting on the bike for the first time after wondering if the chain is going to snap but as long as you follow the instructions to the letter you can ride with confidence!
