Review on 🔧 Bike Chain Repair Tool Kit Set: WOTOW Cycling Bicycle Chain Breaker Splitter Cutter & Wear Indicator Checker with Master Link Pliers Remover & Reusable Missing Connector for 6/7/8/9/10 Speed Chain by Reid Rickerson

The hardware is surprisingly reliable for the price but the tool to knock out the chain pin wasn't exactly, nor was the replacement supplied. Didn't expect the set to work. But it is designed so that when you put the tip of the tool properly on the shaft of the chain, the tip can be locked with the back tensioner to push the chain against the tip, and then the tool will eventually work like a charm . All the extras that came with it were good too.
