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

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 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.

ProsGood Build QualityCan make small adjustments to gradually build strengthEliminates the need to buy multiple gripsWay better than some of the cheaper ones you will have bought or seen which claim to have resistance up to x KG/lbls, trust me they don't.ConsAdjustments can be a bit finicky until you get used to itAlthough good quality its a bit harsh on the hands, expect the odd blister and callouses until you get used to it.Ultimately you get what you pay for. Some of those at £10 or less claim to be adjustable up to 60kg, they aren't and there are youtube videos proving this, they tend to max out at about 25-30kg.My main criticism of these gripers is that they are not very comfortable, but once your hands become hardened to them it shouldn't be an issue.

Well made product seems sturdy and designed well

excellent item and good value

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.

This product is robust and will stand the test of time. However, I don't know if mine is duff or if others have noticed this problem. The wheel used to strengthen and weaken the gripper moves. I couldn't understand why I wasn't making any progress but recently I discovered when I increased the strength and while using the gripper the wheel moved back to where it was before adjustment.

Package and instructions were both purely in Korean, no english instructions available.Packaging also had a Korean website address and a contact email (in gmail, which was worrying)The actual product itself felt sturdy and quite well made. This is the only grip strengthenerI have seen to not have the "pulling handle" pivot on an point, and instead, the whole handle extends and retracts perpendicular to the stationary handle; as opposed to being at an angle due to single point of pivot.A minor issue I have with the product, the resistance is set by twisting the metallic cylinder and pulling the handle makes a small portion of the metal interior arm push against the cylinder. The whole contraption here is greased to lubricate the action, which can sometimes get a bit messy. The metal armalso tends to leave a bit of metallic residue/paint onto the cylinder (both grease + residue can be see on pic 5 provided)A strange thing I noticed was the fact the metallic arm which pushes onto the cylinder is painted black,whilst the other arm is not. Seems a bit strange leave this unpainted....
