4Pcs Finger Strengthener Grip Strength Tester Forearm Strengthener, 6 Resistant Level Finger Exerciser Hand Strengthener for Strength Training, Finger Flexion Extension Training, Black Blue

Whether you already have the Gi Joe kung fu grip or not I definitely recommend this product to make it even stronger. This product is great dor strength training in fingers, wrists and forearms, also seems as it would be good fro anyone trying to recover from injuries in such areas.

If you don’t have small fingers then having huge sausage fingers is hard to put on lol

Exactly as sadvertised. Used for hand/grip strengthening. Appears to be well made. Recommended.

I have three thoughts, 1. Wrong order, 2. Holes too small, and 3. Better than rubber band version.1. My personal order had 3 black and 1 grey versus 2 black and 2 grey. (Simple mistake)2. I returned them because the holes were too small. I feel they triggered an injury adjacent my thumbnails (swollen and tender to touch). I had the pain outside of my nails where the tension was greatest from the gripper.3. I am going back to this device because I got the rubber band type (thinking it would be better) but I didn’t get nearly the range of motion as I bought with these. (Hopefully I figure something out with my thumbs.)

First time using this about a month and a half after I bought it I forgot I had it I used the 21lb mark and I got my fingers in stretched like it said too and it ripped immediately. What’s the point of having horrible stitching and weak material if it can’t be used with the pounds listed.. I doubt I’ll get money back but I seriously wasted it on this … the product by itself without the band seems legit and good but the wrist band itself needs some TLC

Once you get use to it, it becomes more flexible and worth it.

They do work well and strengthen your hand, but leave them on for more than five minutes, and your fingers will turn purple. Overall, 2/5

I have tried three different hand exercisers that focus on opening the hand. Using the wrist as the anchor point is a major improvement over all the others I've tried. I can't speak to the durability, but even if it works for a month, it will be worth the price.
