Bests & Worsts Reviews from Amazon

Pretty neat & really effective! Definitely makes a noticeable difference in the tendons being employed when compared to the single grip squeeze units out there. The ring & pinky finger are sure to feel the burn! Remember guys, there's no muscles in your fingers, they are controlled by tendons in the hand! So the burn will come from inside your palm! The size of your fingers will most assuredly remain unchanged /due to/ this device - but boy oh boy will your grip strength improve! **********MY BEST ADVICE********** Size up what resistance you think you'll want to go with & then pick the size down. It will benefit you much more to be able to accomplish a greater number of repetitions at a lower resistance than it will be to strain your tendons by starting at what could be your max capabilities for some fingers (Sure, your index finger can do the red [7lb.] but can your pinky even get enough of a workout to be beneficial & not simply strain/injure the fragile tendon?) I say all of this from experience with multiple products of different designs after the same purpose. You'll be much happier when your hands aren't in pain from over-exertion - Or aren't discouraged to use it simply because it feels like going from 0-60 rapidly instead of a gradual climb to a beneficial burn. **********MY BEST ADVICE********** Please let me know if this review was helpful to you & feel free to ask any related questions.
