IronMind Grip Strengtheners Editorial Review

The Captains of Crush CoC Key is a tool designed to help improve grip strength and measure progress when using CoC grippers. The Key comes in varying thicknesses to help measure how close you are to being able to close the gripper fully. It's a great tool for those who struggle with counting clicks when using the grippers. However, some customers have found that the Key is too awkward to use for measuring progress when making an all-out attempt with the challenge gripper. The small end of the Key is not functional enough and tends to slip off the grips. The grips should also have grooves to help fit the Key properly. Overall, the Captains of Crush CoC Key is a useful tool to improve grip strength and measure progress when using CoC grippers. It provides great feedback on measurable performance, which leads to sustained motivation. However, it's a bit overpriced for what it does, and the small end of the Key needs improvement.
