Overview
A set of 6 silicone hand and finger exercisers in three resistance strengths, meant for grip, wrist, and finger training rather than a single fixed resistance tool.
Marketed under the seller name Pnrskter with the kind of hyperbolic branding language the actual product does not need to live up to. The core idea is simple and reviewer feedback backs it up: separate exercisers for the flexing muscles that close your hand and the extensor muscles that open it, since most grip training only hits one side.
- 6-piece set, 3 strengths per direction
- Silicone, washable and reusable
- 30-50 lb resistance range
- Compact enough for travel or office use
Who it's for
People rebuilding hand or wrist strength after a fracture, arthritis or tendonitis sufferers doing daily finger exercises, and anyone whose job involves heavy typing, texting or gripping. Also useful for general grip conditioning outside of rehab.
What buyers say
From Amazon customer reviews.
Reviewers used the set for post fracture wrist rehab, arthritis, and tendonitis, several reporting real relief in pain and stiffness after regular use. One stroke survivor found even the lightest resistance too demanding for fine motor recovery, and another reported a band ripping after roughly a year of use.
Strengths and trade-offs

- Six pieces across three resistance strengths for flexion and extension
- Silicone construction is washable and durable for daily use
- Reviewers used it successfully for arthritis, tendonitis, and post fracture rehab

Performance notes
The set covers three strengths for extension, opening the hand, and three for flexion, closing it, aiming to balance the gripping muscles against the usually neglected expanding muscles. Made of silicone, so pieces are washable and hold up to repeated daily use.
