These multitools are a good concept, but generally of poor quality. I've broken the chaintool on three of them, while undoing chainlinks. I had the pin aligned perfectly. It is simply flimsy and cannot take much torque.
Cannondale, if you're monitoring this, please replace these things for your customers with a stouter upgrade, or refund our purchase. This thing is well below the expectations that the Cannondale name sets.
