Made of thermoplastic and steel. This is a really sturdy, adjustable grip strengthener. Feels solidly made, with high-quality materials. Provides between 55 and 154 pounds of pressure. Lifetime guarantee. Built to last.
Some people prefer a stickier or more rubberized-type grip.
Cleanly designed, sturdy metal hand grip strengthener with 5 levels of resistance. Quiet and easy to adjust. Non-slip handles.
Some users find the resistance not great enough, even at the maximum resistance rate. Could break with repeated use as it’s an aluminum alloy.
Industrial hand strengthener with resistance from 22 to 88 pounds. Suitable for hands of all sizes. Includes apparatus for finger exercise and a carrying case. 3-year warranty and 100% dedication to customer satisfaction. How-to eBook included with purchase.
Plastic parts may not hold up as well over time as metal strengtheners. Finger stretcher can break easily in some kits.
3 to 9 pounds of tension per finger. 4 coil stacks target each finger for an even challenge across the hand. Start lower and build: lower levels are more difficult than you might think.
Not customizable; only has 1 setting per device. Not designed to actively work the thumb.
Each ball offers a different level of resistance. Use for hand strength or to relieve tension as a stress ball. Thermoplastic rubber for easy, grippy feel. No latex or BPA.
Not intended for children under 5, as they could be put into the mouth. Lint, hair, and other debris can stick to the rubbery-feeling balls.

Hand strengtheners are used by people looking to improve their grip strength. These are most often used by people with active lifestyles such as rock climbers hikers, bodybuilders, tennis players, and other athletes, as well as musicians. But folks who are aging and have muscle decline or people dealing with repetitive stress injuries like carpal tunnel syndrome also find these to be very useful for physical therapy exercises, and they can even be used for arthritis or post-surgical rehabilitation. Stronger hand grip can help relieve tendonitis, joint pain, and other overuse injuries caused weak hand muscles.
