I’ve found as I get older, my grip is not as good as it used to be. When I seen these, I knew I needed to get them. Not only for working my hands and fingers, but I also seen them as very helpful for my fidgeting. I was right. They feel great in my hands and the little indents make these easy to hold on to. So not only am I strengthening my hands, but I’m also soothing my soul. These are fun to use anywhere…work, in the car, watching tv. The 3 resistance levels should be all you need for healthy hands. The resistance is pretty strong so you can work your way up the levels. In my opinion, these are so much better than the ones with handles that you squeeze. I’ve noticed a nice difference already!
