GD Iron Grip Hand Grip Strengthener (Adjustable Hand Grips for Strength Training) Wrist and Forearm Strength Trainer

EXcellent

Great solid product. Probably the best gripper of all time. But they have the 70, 80 and 90 which leads people to believe that it's referring to build quality. But it's actually referring to the grip intensity in Ibs/kg. I don't know if they are intentionally doing this to get people to buy all 3 of them or not but this take away from the excitement of buying such a great product. They could have just put this in parentheses. This might seem small but it's extremely frustrating.

هذا أفضل اداه التمرين السواعد بس يبيلها واحد متمرس او يكون عندك اداه غيره اذا قوية سواعد تاخذه المقبض مناسب الحجم يدك تقدر تغيره من في قياسين عموم مناسب الى ايدهم صغير وبعد الى يدهم كبيره النقبض من الالمنيوم فيه نتوء مثل الدنابل او البار فالنادي علشان ماتنزلق يدك اذا عرقة عيبه اذا كثرة التكرارت يجرح يدك يبلك تلفها بشريط

Dit apparaat voelt heel solide aan, anders dan goedkopere varianten. Ik heb hem in de standaard staan op mijn werkbureau en het vraagt er gewoon om, om gebruikt te worden tijdens langdurige saaie telefoongesprekken of ellenlange wachttijden. Ik merk dat mijn grip echt sterker wordt, alhoewel ik nog heel ver verwijderd ben van de maximale stand.

Muy bien construido, en general muy satisfecho

Quality materials and top notch design! Easy to figure out without reading the manual. Easy to adjust to different resistance levels. This is a great squeeze! Several positions are possible. Knurled solid bars provide a positive grip. Dual springs design is fantastic.

This is very well made and really tests my grip stength to the maximum. Very easy to adjust the resitance in both Kg and Ib. I have one major criticism but I still give it 5 stars. I use these for stamina ( holding the pressure for over 1 minute) and initially it is so uncomfortable as to make it unusable. I almost sent it back in frustration but a little fix with insulating tape changes the grip comfort conciderably.
