AIXPI Grip Strength Trainer, Hand Grip Exerciser Strengthener with Adjustable Resistance 11-132 Lbs (5-60kg), Forearm Strengthener, Hand Exerciser for Muscle Building and Injury Recover

Gripper is awesome, is adjustable and works just fine at a good price!

Works well, sturdy, adjustable and makes it convenient to use. This has helped me build up my hand strength and grip.

Makes a bit of a clunky noise sometimes but otherwise seems to work well

I saw this on one of the physical therapy podcasts for tennis elbow. I bought it and used it for a week. It worked! Built well and durable. I still use it every day.

Worked well on lower levels, but the plastic ring quickly broke after using it at max level.EDIT: They offered to send me a new one, or a full refund.

I had a wrist injury and have very weak grip strength, so it's hard to find a grip training device that works for me. most start from 10 kg which is too much for me. I love that you can adjust the strength from 5 kg to 60 kg, which makes it easy for me to start training and recovery and slowly progress. I also have very small hands(so small that I often need to purchase child size items) and am surprise that I can grip these comfortably.

They basically do what I bought them to do. They were inexpensive, so keep that in mind. Not the most stable, and I do not believe the resistance scale is accurate, but they provide enough resistance for me, for the moment. I picked these simply because they are inexpensive.

Works great, nice build quality, trains my forearms pretty well.
