Prohands VIA Hand Exerciser, Finger Exerciser (Hand Grip Strengthener), Spring-Loaded, Finger-Piston System, Isolate and Exercise Each Finger

I brought this as a present for my partner who has arthritis to strengthen her fingers it does help but also if you are in pain then probably best not to use unless you have a good day.

Brought this for my dad who had a stroke, helps him with his weakness in his fingers.

After using this for some time, I haven't had any problems with its durability - the construction is simple and sturdy. It's mainly made out of plastic, but the palm part is comfortably padded. The whole device is a bit small - something to consider if you have larger than usual hands.

Very good.

really helped with my stiff fingers

what you expect used daily to strengthen skills on my banjo, very happy indeed, comfortable too! a a aa a

really cool ,lets you practice your scales and keeps your fingers working well,ie builds up your sensitive pads.i keep it in my pocket at work,practice my scales when walking about.the way to do that is say ?you want to learn a D major scale it would be 2-4 1-2-4 1-3 1-3 1-2-4 1-3-4 and so on,you begin to see it in your minds eye.very handy to have.thanks too Elia for my gift ***

It Does what it says, but i find that as a guitarist it doesnt have any use because it ends up damaging your fingers rather than building their muscle. I would advise a pass on this from a musician point of view, and it does not help RSI. (i am developing RSI and this makes it worse)
