I don't understand the low score for this product?
There is nothing wrong with it at all. In fact, it's a great product that does what it's meant to do. It's one of the few products that helps you train antagonist muscles rather than just your grip strength. The fact that it does both grip strength and the antagonist muscles in one package is great though. It also does it a way that feels very friendly to your muscles. You yourself can easily determine how much force you would like to apply and for how long.
I would highly recommend them even if you only use them a few minutes a day.
