GD Pro-70 Hand Grip Strengthener (Adjustable : 55~154 lbs) Hand Strength Trainer Wrist and Forearm Training Equipment Hand gripper

I bought this grip so many years ago that I don't even remember if I bought it on Amazon. I have been using this regularly since 2012 or 2013 and it is working fine so many years later. The wheel can make it heavier (S- stronger) or lighter (W- weaker) and the mechanism is still working properly. But be aware that you can only adjust it in general Heavy/Light steps, you will not be able to set precise weight. But as an auxiliary exercise or a substitute for stress ball, it works well. It has helped me increase my grip strength, so much so that during a routine fitness test, the nurse asked me to perform the grip strength test three times to make sure that their calibrated instrument was indeed right. I don't remember how much I paid for it, but anything that can last more than a decade is worth the money.

Very good quality, and even after years using there still no problem.

Het is niet goedkoop maar wel top kwaliteit

Llevo un tiempo usándolo y llegó a la conclusión de que es tremendamente bueno es silencioso a más no poder buen agarre se cambia de posición con la rueda que tiene en el frontal y el muelle de resistencia te pone en tu sitio real no como otros que he usado que ya sea con un muellecillo y otros que no tienen tensión y al poco rato hacen ruidos y se atascan este es solido y silencioso

Diger standart olanlarla karsilastirildiginda inanilmaz zor. Digerlerinin 60kg gosterdigini yapan bu aletin baslangic seviyesinde bile zorlanabilir

Hay muchas opciones más económicas de este aparato. Sin embargo, el diseño y la calidad de los materiales hablan por sí mismos, por lo que vale la pena invertir un poco más y adquirir este producto 100% orginal de GD Grip. Sobretodo si tu objetivo es solo fortalecerte por un problema de tunel carpiano.
