GD Hand Grip Exerciser Strengthener (Premium Adjustable Hand Gripper) Wrist and Forearm Strength Trainer

Ergonomically far superior to the common, generic design offered by most other manufacturers. Easier, more consistent, comfortable and sustainable grip plus far easier to position correctly in your hand. A little more expensive yes, but it's definitely worth the few extra quid! Definitely recommend.

I must say it’s one of the best gripper on the market. Hand span can be infinitely adjusted with great precision. Spring tension is easily adjusted by front knob. There is no clicking sound as in many Chinese cheap copycats (avoid). Very good grip in hand - no knurling on front handle giving it a very good feel in hand. Simple sturdy and light construction -not too heavy as other GD gripper. Needs a bit of grease from time to time on the main nut to keep it running smooth but this is not a problem and it’s very easily done with perfect access. Best feature to me as compared to other grippers on the market is that the handles compress in parallel rather than at an angle as in standard simple grippers. This gives a great feel in hand and it’s properly ergonomical giving uniform action when compressing. Not the cheapest gripper but I don’t regret buying it. Great product from GD Korea.

I'm satisfied with this hand grip. Can be tough on your hands if you don't use gloves. Very solid and well made.

Great kit, really happy with this. Ergonomic design, adjustable strenght. All previous devices I had were specific in power, this one adjustable, work even after you have injury.

I have previously had two adjustable hand grip trainers of a cheaper variety, and in both cases the spring broke after some use. It's easy to see that this model has a much sturdier construction. The plastic is hard and has a good structure and finish. If you look at the picture, you can see how the handles are constucted, and the internal walls make them much harder to break. The design is superior to other models, and by having a sturdy spring that compresses when used, there is almost no chance of it snapping like in the cheaper models. It's also fits nicely in my grip, and adjusting it is very straight forward. You simply turn a metal wheel that adjusts the angle of the spring, therby making it harder or easier to compress the grip trainer. There is even a scale in both kg and lb to keep track of your progress.

Only for those at top level. The minimum resistance is too strong for me and I find it spins in my hand if I don't use the other hand to steady it.

Bought as a gift for my dad in his late 70's who is determined to maintain his fitness and mobility for as long as possible. Suffering from years of hard work his hands are a little arthritic but this device allows him to maintain and improve the flexibility and maintain his grip strength. It's fully adjustable for all abilities so you can start off easily and increase the pressure as you improve if necessary.

Very good. Happy with the product - it's manufactured to a high quality. The red rubber grip slips a bit but can be pushed back into place. I'm trying to decide whether my grip has been getting stronger or the spring has already started to weaken after a few months of usage. I used my partner as a comparator and, despite never having exercised with the device, to my surprise they can now fully close the grip on its highest setting with their weakest (left) hand, which could certainly not do when I first took delivery!

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

I've had my GD Grip Ultra 70 exerciser for a little more than 6 years. It is very durable. I especially like how the grip handles stay parallel throughout the exercise. Both the resistance and the grip size are adjustable. The front black knob adjusts the resistance while the silver wheel adjusts the grip size. When the front knob is turned, the spring compression is changed, changing the resistance and moving the bolt forwards or backwards. That also moves the silver wheel the same distance which changes the grip width, which then must be readjusted. For instance, if the front black knob is adjusted 1/2 turn clockwise to increase resistance, that moves the bolt forward and compresses the spring. Then the silver wheel must also be turned 1/2 turn in the same direction to maintain the same grip width as before. Otherwise, increasing the resistance will decrease the grip width making it generally easier, while decreasing the resistance will increase the grip width which makes it generally more difficult. So, the key is to turn both the front knob and the silver wheel the same amount and in the same direction to keep the grip width the same while changing the resistance. Turning the silver wheel to widen the grip will also increase the resistance. This occurs because as the grip gets wider, the cam pressing against it to compress the spring moves horizontally and feels the full force of the spring. When the grip is narrower, the cam moves at a more downward angle giving a mechanical advantage over the wide grip when compressing the spring. It also means that as the grips move closer together, the required force to close the grips becomes less. So, the resistance level isn't linear over the full grip range, though this isn't obvious when using the device. Things that could be better: 1. The grips are hard plastic, and at higher resistance level might be a bit uncomfortable and a bit slippery. Workout gloves should help with comfort when needed and friction tape should help with slipperiness. 2. The front knob resistance adjustor doesn't stay set very well. It is just a nut on a bolt. When the grip is flexed, the nut moves forward and can easily turn on its own, changing the resistance. If you like to work with progressive resistance, that will undermine the effort. I wound Teflon thread tape around the bolt 15 or 20 times (it's thin) and then put the nut on. That gives it enough resistance to keep the nut/knob from turning on its own while still allowing it to turn easily for adjustment. I highly recommend this grip exerciser for its stable, parallel handles during use, and for its resistance and grip width adjustability. It has a wide range of resistance, though the lightest resistance might still be too strong for many women and boys.

Extremely good quality, adjustable strength, made in South Korea.

Het is niet goedkoop maar wel top kwaliteit

Very good product
