Great for a repair kit to keep on your bike.
Great little kit, everything you need, nothing you don’t. Add some oil, and this is a great little kit to keep on your bike. Quality is good, and overall an excellent value.

Chain breaker handle broke immediately
Chain breaker handle broke almost immediately. I suspect the chain wear tool isn’t the proper size but the master link pliers were of ok quality. It works at the very least. Kinda worth it just for the pliers and the 4 master links but I don’t know how much I would trust the links

They only work if there is a master key in the chain. If you have a chain with no master key they don’t work.
