6/5 if I could

Best purchase of my life. Game changer for measuring and making progress on grippers I either can’t close yet or don’t feel comfortable closing for multiple reps.

An important CoC tool for serious gripping achievements

Superb for measuring progress and sustaining motivation.

Very useful when jumping a level before you can perform consistent clicks. Measures your progress in a meaningful way until you become able to count clicks. Also use as a one- or two-crush test on the next level up with CoC grippers. Great feedback on measurable performance leads to sustained motivation. Crush-em.

The Key to knowing where you are at.

This high quality product is a great addition to anyone's grip training program. This is a must have to determine and track goals of being able to close the COCs'. It always provides a unbiased uniform method of tracking advancement and progress toward success of closing the COC Grippers. The product is well made and durable in structure and is the perfect size to carry in your gym back, or in your EDC pack. The fit and finish is the quality that you could expect for IronMind product.

What the hell is the point?

If you can't close the grips all the way then close them as much as you can. Eventually you'll get stronger.If you really want to waste $13 on some pointless extra piece of equipment why not just get 13 single dollar bills and roll them up into a small tube? Use that between your grips.This does absolutely nothing that you aren't already doing except take your money and make a tiny "clink" sound.
