Im deploying to Afghanistan next year and wanted to strengthen up my grip and my trigger finger. This product has definetly improved my hand strength capabilities and also has helped make my trigger squeeze smooth and and easy. I am very greatful for this product and cant wait to head back to war.

I love this little device. I only purchased it to build my fingers up for better typing and it did just that, but it did more. I have stronger hands, fingers, and people are afraid to shake my hands. I think that's their way of telling me to move up to the extra heavy tension. I might just do that. Highly recommended.

Hand exercise is nothing new to me, neither is most other types of exercise or workout. But the loss of hand movement is a scary thing.

This time around I damaged a nerve causing severe restricted finger movement. So I forced myself to move the fingers as much as was possible. As the nerve repaired, finger movement restored slowly (1/32" or less a day). I believe my constant aggression may have helped. But during this time my fingers became lapse from their 'sleep' time and needed to be worked back to normal, and muscle memory re-gained.

Since I utilize single fingers, some fingers more than others, this exercise devise not only got each finger up to speed it improved their use like never before... Needless to say, if you don't do it it won't get done. And that's just the way it is.

For those familiar with regular squeeze devices, this device can perform that way also, naturally.

Does it work? Does it help? Without a doubt.

The only choice to be made is the amount of resistance in pounds you require. I started with 9 pounds dubbed Heavy tension. After the fact I went and got the 7 pounder. I gave it away. But that's me.

There's a plus of portability. I didn't mention this but your regular hand squeeze devices have a varying grip and are problematic to smaller sized hands. The Gripmaster doesn't have this drawback at all, small, medium or large hands. All are good with this one device.

The gripmaster pro works the muscles of the hand and forearm well but for someone who has small hands,I find the pro version is a bit too big. The regular version fit my hand better but if you have average or big hands, the pro version would be right for you.

I had 2 of these gripmasters from about 8 years ago. One of em I lost a long time ago, but the heavy tension traditional black model gripmaster i had held up under almost constant use the entire time, until about a month ago when the little internal plastic spacers started breaking out and it became very hard to use(although still usable). These new ones seem much higher quality, and although the pad for your palm on the back is taking a little getting used to, I am liking them very much. Excellent Workmanship, excellent product.
