Digi-Flex Green Hand and Finger Exercise System, 5 lbs Resistance

I broke my finger a few months ago & needed surgery and physical therapy (still in PT). I've managed to get most of the contraptions that my therapist, uses. This is one the most useful gadgets that she uses on me, so I found one here for home use. WOW! It is working like a charm! My singer's. strength and dexterity have greatly improved. My therapist says that it's especially useful for musicians, especially guitarists who have injuries, carpal tunnel syndrome and mild arthritis. I'm none of the above, and could've made do with therapeutic putty. Despite that, I'm very happy with the purchase. It's sturdy, and it arrived ahead of schedule. My ONLY regret is that I didn't buy a set because my fingers have nearly outgrown this one & soon I'll need one with more PSI. It's a wise investment for those who have my above listed finger ailments.

Muy buenos cumplen la función y lo prometido

I absolutely love this. Simply keep in your car and work out hands/wrists flexors and extensors while you drive. Great build quality. I truly appreciate working out each finger individually and focusing on median and ulnar sides. it can even help your carpal tunnel and video game controller strength and response timing. If you want to be a strong as ever this is fantastic!

Très bien, j'aime beaucoup son efficacité.

Got this as a gift for my husband and he loves it! He has problems with some of his finger joints, so the separate springs allow him to work his fingers individually and focus on problem areas as needed. Too bad it isn't sold as a pair-- it would be faster to work them on both hands together, or let someone else use one! (I haven't seen it since I gave it to him.) ;-)
