I bought this item couple weeks a go to test out my grip strength. Since I was only using the 100lb and 150lb hand strength grippers, I was never able to figure out my actual grip strength accurately. But with this item, I could figure out my actual grip strength with accuracy. I recommend that you buy this item if you are training at home casually. With this item, you will no longer be working with grippers that are not in your range.
For a while I have been looking for a tool that would accurately measure my grip strength. I have finally found the perfect one!
