Prohands PRO Hand Exerciser, Finger Exerciser (Hand Grip Strengthener), Spring-Loaded, Finger-Piston System, Isolate and Exercise Each Finger, (11 lb X-Heavy Tension, Black-Pro Rehab)

great if you are rehabbing or starting off rock climbing. Take it from somonme who keeps buying these, buy the heaviest tension one you can find right off the bat. I have a medium and xheavy and you need get adjusted very quickly and are ready to go up.

This hand exerciser is unreal. It has done wonders for my hand which hurts a lot because of typing at a keyboard all day long. Excellent product, well made and couldn't be happier.

These are really great to have, I just wish the resistance was a little stronger. I got the Extra Heavy and I was expecting to struggle with them. I'm 58 years old and have arthritis. I admit that I'm 6' 4" and still have some strength in me, but I wanted something that would cause me to work a little more. I use them at home and at work and my hand joints crack less when I use them. I also feel less pain after using them.

Great for training individual finger strength!

I recently had carpal tunnel surgery. I use the same tool at the physical therapy. I am using this at home to strengthen my fingers.

Gift for my high school football player. He likes it, I'm happy!

Works okay, but a could be a little more stable.

Good condition, works great, on time delivery…Thank you!

Benutzte ihn für das Boulder-Training. Die Finger lassen sich sehr gut einzeln trainieren durch verschiedene Übungen. Der Gripmaster ist gut verarbeitet und liegt gut in der Hand.

Efficace dès la 1ère semaine pour les mains et les avant-bras (au moins). Construction a priori solide. Beaucoup de positions possible pour une musculation y compris du pouce et des bouts des doigts en pincement.Ne permet pas de s'exercer au rapprochement des doigts mais ne prétend pas le faire. Je réserve un Power Putty (cher!) à ça, par ailleurs inefficace pour la musculation de la main réalisée par ce Gripmaster.Très bon achat, toujours dans la poche, utilisable au bureau etc.

Good product that allows you to train each finger individually, which is a major plus.However, it's just does not have enough resistance.Having somewhat of a weaker grip, I was reluctant to buy this 11lb, x-heavy resistance version, but having bought grippers in the past that did nothing for me, I decided to take a risk and go with this x-heavy version.Well... it's still no strong enough and keep in mind that statement comes from a person with a weak grip.So it's a quality product, well build, good design, but they really need a heavier resistance version.The springs could be a little longer in extension too, allowing for a longer range of motion. I have a small hand and still find the range of motion rather short, so I can only imagine what people with long fingers make of this.Still, a very good product.Recommended.

Ich benutze insgesamt 4 der Gripmaster, Pro blau (light), rot (medium), Schwarz (x-heavy) und Braun (xx-heavy).Blau = zum erwärmen der einzelnen FingerRot = zum Training mit hoher Wiederholungszahl der einzelnen FingerSchwarz = zum "harten" Training der einzelnen Finger und "Beginnersätze" für die ganze HandBraun = derzeit nur Handtraining.Qualitativ sind die Teile sehr gut, auch das Handling ist sehr gut.

Eignet sich recht gut um die Handkraft beim Bouldern o.ä. zu steigern. Verarbeitung recht ordentlich aber die Federn "knarren" etwas. Mal schauen on hier Silikonspray hilfreich ist. Prinzipiell sollte man als Mann zur stärksten Variante des Gripmaster greifen, da sonst der Trainingseffekt zu gering ist.Einziges Mango....der Versand durch Amazon hat sich über 2 Wochen hin gezogen...wer weiß wo dieser Gripmaster her geordert werden musste
