GD IRON GRIP Grip Strength Trainer Adjustable Hand Gripper Strengthener Hand Grip Exerciser Wrist Strengtheners Silent & Durable – Forearm, Finger & Hand Strength Training for Athletes, Climbers & Rehabilitation

This is a great quality gripper!Heavy build but sturdy and will last a lifetime. Easy to use and to adjust between resistances. I am up to 75 lbs. after a month, working to get up another notch for 10+ reps. I don't foresee getting to point where the resistance is below my strength.Grip is knurled so it can be a bit uncomfortable. I added the padded grip to these, very well worth it. Straight bars are still a bit awkward at times, but that may just be me.Well worth the higher price, my trust in the other options out there was slim so glad I paid the extra for these!

Not saying anything new here, but just to echo other reviews with my experience: this thing is a beautiful tank. Very smooth, very sturdy, and very effective. Like others, I was about to buy more of the $7 cheap plastic ones that threaten to throw springs and plastic in your face when they inevitably explode, when I saw the Iron Grip. I took some time to try and figure out which model (80 or 90) and whether I wanted the extensions and stand base. Decided to go with the 80 with the extension. I have medium glove hands, so as others have said, I didn’t need the extensions for comfort. However, this thing has some serious resistance and only 6 slots, and I’ve found that the extensions are great for working up to a new weight. You can start all the way down at the extensions with your grip which makes it a bit easier, then progressively move upwards on the handles towards the spring, making it harder. The 90 was tempting as it offers higher resistance, but honestly I don’t know if I’ll ever make it that far. Not using this for any weight lifting competitions, just strengthening my hand decades after metacarpal surgery, and generally strengthening my arms, so I won’t need nearly 200lbs of resistance. But if I do, this thing is so gorgeous and well made, I’d be more than happy to pony up again, this time for the big boy.

The best grippers I've ever used, by far.Solid build, excellent ergonomics, straightforward adjustments.The price is high, but justified.I started with a pair of the 90s, but found I didn't need the extension or the extra 22lbs. of resistance (I should have listened to other reviewers who said as much). These offer much more resistance at their 84lbs setting than a far cheaper adjustable plastic gripper at its supposed 80lbs., so bear that in mind if you're testing cheaper ones at a box store to determine the max resistance you need like I did. I did not test either to determine the accuracy of their given settings' poundage. Just know that these grippers are harder than one other new cheaper pair. Other reviewers write that they've had similar experiences. Finally, the lowest setting (55lbs) matches the resistance on my old gripper in the picture that's been well used for about 10 years.After a brief test, I returned the 90s thru Motofitusa & Amazon easily and only had to pay return shipping (around $6 FL to NY). I then got a pair of the the 80 Lights on prime day for nearly $10 off each, saving roughly $53 total.On both the 90 and 80 Light, the knurling is the same and ideal: small crosshatch size matches the exercise (for example, dumbbell knurling is a larger and deeper crosshatch and barbells sometimes are even larger and deeper than the dumbbell knurling). I had a much better grip on the 80s than my old plastic grippers, and it did not hurt my hands or damage my skin.Lastly, there is a good jump in resistance levels, but I plan to further break the 6 levels of resistance into 18 levels using the 3 levels of grip size. If I can't do the largest grip size at the next highest resistance level, I'll simply close the grip size to the smallest setting, simultaneously increasing the leverage of my grip and reducing the range of motion in order to complete the exercise. As strength grows, I'll increase the grip size to the medium level and finally the largest level, and then repeat for the next resistance level--pretty straightforward progressive strength training.Thanks again to Motofitusa for a stellar product.

This is a well made piece of equipment that will last years. The all metal construction gives it a cool industrial look. It's made in Korea and it shows. The adjustable weight settings allows for continued muscle development. Which is great considering this grip on the expense side. My only negative is the knurled handles due hurt your hands but that can be mitigated by wearing gloves.

Great device, it is really smart engineering design and well built. Quality from older days which is really rare nowadays!Not sure why shop is not updating pictures of the product. Because I’ve just received IG80.2025 and it is much cooler compared to what is presented on this page at the moment of writing.It has dual adjustment marks for A and B positions.Basically this tool has at least 36 levels of adjustment 2x6 for A&B, then x3 for width adjustment

The quality seems good, it's smooth operating and I expect it to last. Changing the tension is a little fiddly but works ok and not something I plan to do frequently. The grips are a bit rough as I see others mention; i would plan to cover them unless you are looking to roughen up your hands. I was thinking of trying racquet grip tape but I had a couple foam bike handlebar grips which I cut shorter but they were also a bit too small in diameter to slide on so I cut a slit lengthwise and they went on easily with a sight gap which I rotated to the insides so my thumb and fingers don't notice. Overall I would give it a thumbs up as a premium gripper if you can fix or accept the handle roughness.
