I got this for Christmas many years ago. I did not do a lot with it until this year. Now I am using all of the different grip attachments and strengthening my overall grip with these pieces. Solid steel construction. Variety of different grip attachments.
Now, I tend to like to start heavier on some of the implements, and so I use a special custom loading pin that I had made that is 125lbs empty.
My favorite out of all of them is the ball. Now I may not do it as for a grip contest, but I do it to help strengthen my grip overall. The pinch grips are hard, but the 1" block there is the best.
