Overview
A double sided finger and hand exerciser with six adjustable resistance levels, made for grip training, hand therapy and rehab work such as carpal tunnel or post surgery recovery.
The dual sided design mirrors the same resistance setup for left and right hands, and the hook position changes let you step up from 6.6 to 21 pounds as grip strength improves. Reviewers who used it for surgery recovery and age related hand stiffness reported real benefit, though several also flagged the finger caps and rubber bands wearing out within days.
- Dual sided design for left and right hand
- Six adjustable resistance levels, 6.6 to 21 lbs
- Aimed at hand therapy and rehab use
- Also used for rock climbing and instrument practice
Who it's for
Fits people rebuilding grip after injury or surgery, older adults dealing with hand stiffness, and climbers or musicians wanting light finger conditioning. Less suited to lifters chasing heavy grip strength, since the top resistance tops out at 21 pounds.
What buyers say
From Amazon customer reviews.
Several reviewers used this for physical therapy and surgery recovery and said their hands and wrists felt noticeably better after regular use, including one older reviewer using it to keep hand muscles from closing up. The recurring complaint is durability: multiple buyers reported the rubber finger caps coming loose or falling off within one to two days, and the bands on the finger grips tearing or stretching out after just a few uses.
Strengths and trade-offs
Drawn from this product's published specifications.
- Some reviewers found rubber bands wore out within days
- Finger caps reported to come loose after a few uses
- Not built for serious heavy grip training
Performance notes
Six resistance settings, split across a light grey set (6.6 to 11 lbs) and a heavier black set (13 to 21 lbs), let users progress by moving the hook rather than buying a new device. Reviewers used it successfully for tendon surgery recovery and stiff hands, describing gentler results than a full grip trainer, though a few reported the rubber finger caps detaching or the bands stretching out within two to three days of use.
