Gripzilla Spinster

High quality training aid.

First, I believe the quality is good. For the price I think this was reasonable compared to the IronMind Twist Yo Wrists. I have 3 things that I dont like. 1) The length of the rope should be about 6 inches longer. 2) The original knot on the carabiner wasn’t the greatest. I replaced it with a bow line knot. Seems more sturdy. 3) There are burrs on the inside lip of the handles that could mess people’s hands up. If I couldnt fix the burrs my rating would be 3 stars.

This is a very good device. It does exactly what it's designed to do. Great challenge for the hands, wrist and fingers. It's easily adjustable. Just add weight
