I love the superr light weight, but it comes at a big cost. The whole point of a chain breaker to be able to crank on it and pop your chain pins out, right? Well, this motion pro tool is not strong enough. I bent the pres metal piece and started to damage the thread don't he tool itself with minimal torque... and the pins did not even move!
I then pulled out my fat see one and whale, no problem. I will be getting rid of this nad not carrying it, bedauseit doesn't do it's job and I would not trust it in the trail. Also, it's expensive AF.
Do yourself a favor and buy the tusk or MP $20 steel one and have it actually work. The extra weight is worth it if you need the tool.
Not that it's common for me to remove a chain on the trail, but o-ring chains are a pain to remove and install master links without this tool. Not for daily use in your shop but occational use would be okay. Very compact and light. A good item to keep in your trail tool pack.
