Price range: See on Amazon
What we liked
- + Pro Edition build is meant to last longer than the standard plastic model
- + Independent pistons let you isolate weak ring and pinky fingers
- + Quiet, pocketable tool for desk or couch finger work
Trade-offs
- - Pick the resistance level carefully to match your grip strength
- - Piston pressing trains finger flexion but not open-hand hang strength
