Review on Bike Chain Tool Kit with Bike Link Plier, Chain Breaker Splitter, Chain Wear Indicator and Checker - Ultimate Road and Mountain Bike Chain Repair Tools for All Models by Mark Toth

I bought this mainly because of the circuit breaker and pliers, the rest was extra, I thought it was good value for money. The pliers work, but the circuit breaker sucks. I thought I was doing something wrong because the knob didn't rotate past a certain point. I was so frustrated because it seemed like I was doing everything right but it wasn't working. I noticed that the pin doesn't come out straight, it comes out crooked. I ended up buying another tool and then I was able to get the job done. I'm sending it back because it's junk and mine is useless. I would recommend using a higher quality circuit breaker.
