This is not just an ordinary hand gripper it’s a work of art. The finish and level of craftsmanship are truly satisfying; this gripper is simply beautiful. Back when I was in the military, I used the ones with horizontal springs, but this can’t even be compared to the GD Grip models from those days. GD Grip, a company that has dedicated everything to developing these tools, has finally perfected it. I understand why so many international YouTubers make reviews about it. I especially like that when holding it in the right hand, the front side displays pounds (lbs) while the back shows kilograms (kg). I doubt a complete beginner would buy a machine like this, but since everyone is used to pounds, choosing to place the lbs markings on the front side when held in the right hand was a great decision. The included stand is excellent as well. Maybe I didn’t capture it perfectly in the photos, but in person it even looks great as an interior decoration piece. It’s genuinely beautiful I made a great purchase, and I’m proud of myself for choosing it.

Customer Reviews
Taken from the manufacturer's official online store.
View original reviews on the manufacturer’s website ↗It is sturdy and well made. My child likes it very much.
It is massive and looks luxurious.
I bought it after Gemini (AI) misled me by claiming that, for example, you could set 4.5 levels by placing the left side on level 4 and the right side on level 5, and then gradually increase the load during training. Anyway, I’m not going to take product recommendations from any AI from now on you should take them only as a reference. That said, the product itself is good. It has to be, given how expensive it was. A regular A-shaped hand gripper with 150 lbs (67 kg) resistance I can squeeze with some effort, but this one I have to use with extended handles even though it’s set to only 51 kg. That probably means the values are closer to reality. However, that also makes it seem unnecessary to buy the version adjustable up to 90 kg. If someone can actually squeeze 90 kg, then they’re basically a Hulk in human form. Because of Gemini, I thought I would be able to increase the resistance in 5–6 kg steps, so I said to myself: “Okay, I’ll get the 90 kg version.” But honestly, the 20–70 kg version is more than enough for you unless you are absolutely certain you can handle 70 kg.
The durability seems good and the build quality is truly luxurious. As expected, it is excellent.
