Hand Grip Strengthener, Forearm Strengthener Adjustable Resistance 22-220 Lbs (10-100kg), Grip Strength Trainer Kit with Automatic Counter for Strong Wrists, Fingers, Forearm, Hands-Black

Good stuff

I haven't been using this for long enough to say my grip strength has improved yet but I'm confident it will. These is a good range of resistance and is simple and easy to use. Well priced. Very happy.

The gripper itself is satisfactory; however, the claim that it offers up to 100 kilograms of resistance is undoubtedly inaccurate. I am able to perform multiple repetitions with this device on the max resistance, whereas I am unable to achieve the same with a 100-kilogram gripper from a reputable brand.

Grip feels nice, and adjusts really well. But the tension is no way 100kg. I've got a dynamometer that puts my limit at 50kg but I can this one with ease.

Just so you know, I review products for Amazon, so I did not pay for this item. Having received it, here's what I thought:I've tried a couple of these devices. This has a good range of grip pressures, I don't have the ability to check that it's 10kg at one end and 100kg at the other. I think it's probably not 10x at 100kg end, but there's a good range of difficulty. The device works well, it lives on my desk and I click away at it during meetings. The counter is good, but it's a little hard to read, I'd prefer a digital counter (so took a star).
