Hand Grips Strengthener, Adjustable Resistance 22-88 Lbs, Hand Exerciser Strength Trainer Hand-muscle Developer , Build Hand Finger Wrist and Forearm Strength Easily

Product comes in great shape and works as expected. I've had it for a couple weeks now and I think the whole forearm muscle thing is a gimmick. You're better off in a gym. That is not the products fault so I will not be critical of that. This is more geared towards elderly and people with weak grips. Its more of a rehabilitation device than a muscle builder.

The screw mechanism in the front was a bit jammed at first... but maybe that was a test, right? LOL I use them watching tv... up to 100 per hand and I really enjoy them! Get a grip on your handshake and purchase these for yourself now!

The adjustable tension on these grippers is really nice. You adjust the tension as your grip gets stronger. This one is very nice.

Easy to use, like the fact that it's adjustable. The handle is a little short, but still works well. I like this when I work on my computer mouse/keyboard as it helps with the fatigue I get when I'm working on editing pics. Would recommend this.

Excellent way to strengthen hands, wrists and forearms. I previously purchased one of these made by ACF. The spring broke after 10 months. This one by DONGJI is a very similar design as the ACF one but the grips are covered in a soft rubber making it very comfortable to grip.

I fined these grips perfect for me. I am 61 so they work great. If you work out often these are not strong enough. I have trouble with weekness in my hands since my heart attack and the Dongji grips work great for me getting strength back into my grip.

Works great. Nice that you can set the force of the pull you want

Funny manufacturer name - don't let it fool you. It will pump - your hands up.After using this product I now have a most excellent and manly handshake.Guaranteed to get you a promotion at work within 3 months of use!
