NIYIKOW Hand Grip Strengthener, Grip Strengthener, Forearm Strengthener, Adjustable Resistance 22-132Lbs (10-60kg), Perfect for Musicians Athletes

I purchased this grip strengthener to improve my forearm strength for rock climbing. I wanted a simple tool that I could keep at my desk or by the sofa to get some passive training in while working or watching TV. I have been using this daily for about three weeks. I usually do high repetition sets on the lower settings and shorter sets on the max resistance. Performance and Experience The standout feature is the adjustable resistance dial. It allows you to change the tension from very light (22 lbs) up to quite heavy (132 lbs) just by twisting the knob on the front. This is excellent because my partner can use it on the lower setting and I can crank it up for myself without needing two different devices. The handle has a rubberized texture which makes it comfortable to squeeze even when the resistance is high. I was worried the plastic might dig into my palm but the ergonomic shape fits the hand well. The spring mechanism is smooth and surprisingly quiet so it does not annoy others in the room when I am using it. Pros • Adjustability: The resistance range is wide enough to cover rehabilitation needs through to strength training. • Ergonomics: The non slip rubber handles prevent the tool from sliding around in a sweaty hand. • Build Quality: The spring feels robust and the tension has remained consistent so far. Cons • Scale Accuracy: There are markings on the side to show the weight but it is hard to know the exact poundage you are at. • Handle Width: People with smaller hands might find the reach a little wide when the device is fully open. Verdict This is a high quality training tool that does exactly what it promises. It is sturdy, versatile, and effective for building hand strength. I would definitely recommend it to anyone looking to improve their grip.

Good adjustable tension and resistance. Great to end the day with to improve grip strength.

I picked up two of these, given the relatively cheap price, and was pleasantly surprised by what I received. These grip trainers are quite well made, with a fairly sturdy construction that feels solid in the hand, though admittedly the handle itself is not as ergonomic as it could be. It also comes with a small sheet of recommended grip exercises, a great inclusion for someone who wants to diversify the grip exercises they're able to do. The springs that supply the tension feel solid, I don't forsee any issues with them for a long time. Given their size, these are nicely portable and could easily be taken almost anywhere. My only complaint would be the adjustment knob. You turn it to adjust the weight between 10kg and 60kg, but the knob itself is not that smooth, feeling a little bit rickety when adjusting the tension. Between this and the slightly uncomfortable handles, the product isn't perfect, but is great for the relatively cheap price and will be more than enough for 99% of people

Really good product, sturdy, great design, easy to use

Excellent piece of kit. Variable resistance settings. Cannot fault it.

Due to recently damaging my arm i was worried about muscle wastage and wanted something to keep my arm active, so ordered these and got them next day. Honestly for the price they are ok, i am a 40yr old guy who is naturally strong, these may be a but much for some people. The adjustment on them does very little (if anything) and i feel its more of a gimmick feature to sell them rather than a functional feature. But yea ok made, cheap and for me the right amount of friction, result.

Sturdy design with adjustable resistance which can be tailored individually. Effective product which builds strength. Easy to use in both hands. Good value for money.

Decent product for working on your grip strength. Easy to use and fits perfectly in your hand (I’ve got rather small hands). Can use it on the go where ever, the only downside for me is the material being rubber means your prone to getting blisters on your hands if you use it too much
