Gripmaster Hand Exerciser, Finger Exerciser (Hand Grip Strengthener), Spring-Loaded, Finger-Piston System, Isolate & Exercise Each Finger

Well made works well for me

The gripmaster finger exerciser is great for those looking to work on finger strength and overall grip. BUT...please realize that these are not designed for whole hand strength work. They are designed for individual finger work. If you are looking for whole hand grip strength training, you should buy a different device. I see people reviewing these devices saying that they are super easy and not worth the money because they can do like 150 reps on the black (heavy) tension. This is because those people are using this device as a whole hand grip strength trainer instead of a finger grip strength trainer.If you are looking to increase your finger strength/dexterity, these are great devices. And as you increase your finger strength, you will automatically increase your overall grip strength.I have been using these gripmaster exercisers for about one year now and I am a normal, 6 foot, 200lbs male. The reason I began using them was I started to have shooting pain in my forearms from the beginnings of carpal tunnel syndrome. I figured that if I strengthened my hands and forearms, I might have less problems with carpal tunnel. I started with the blue (light tension) gripper and moved up to red (medium tension) after about 4 months of moderate use. During this time, I tried my best to do all the exercises shown on the Gripmaster website: [...] My routine was three sets of decreasing reps once per day. 15 reps followed by 12 reps followed by 10 reps holding each finger or grip hold for 5 seconds.After 4 months I went to the red (medium tension) device and continued my routine. By this time (4 months after initial use), all my pain associated with carpal tunnel syndrome was gone. After another 4-6 months using mostly the red device, I decided to try the black (heavy tension) gripper and purchased the black and red combo pack even though I already had a red device. The black device was challenging and still is, but I can still do my normal workout routine with it and it has increased my grip strength even more.The interesting thing was that the new red device was much stiffer than my old red device. This was the first time that I realized that these Gripmaster devices "wear-out" fairly quickly with normal use. By wear out, I mean that they lose tension and become easier to compress over time thereby giving you less of a workout. As best I can tell, within 4-6 months of normal daily use, the tension will be significantly lower than when first purchased.Overall, I don't like that the tension drops off fairly quickly under normal use. But I cannot argue with the results and that is really what matters. As long as you are willing to replace the devices every 6 months or so, you will be very happy with the results from the Gripmaster. I give these devices 5 stars because they do exactly what they are designed to do and strengthened by hands and rid me of carpal tunnel pain. My hands and grip feel stronger and as a bonus...I've found that the hand exercises provide some stress relief as well.Bottom Line: If you want stronger hands, fingers and grip and you are willing to do the exercises as shown on the Gripmaster website, then you should get these devices. I would suggest that all normal adult males should start with the red (medium tension) and go from there. If you are already very strong or already do hand/finger workouts, you may want to start with the black (heavy tension). If you are rehabing an injury (like I was) or are very old or very young, you should probably start with the blue (light tension) device and work your way up. I would also suggest the blue device for normal women to start with. Women who already do hand/grip work could probably start with the red device and move up from there. Thanks.

I ordered this grip master ten years ago. I didn't think Amazon would have the order history for items this old let alone be able to leave a review for it, but here I am. Anyhow, I want to say that I have used this device regularly and it still has the same strength since I bought it. Not only did I use it. But my friends and son plays with it too.I bought three different strengths / tensions of these 2 years back, and based on the strength of those, this one has not lost any noticable spring retention. The build quality has held together very well and the rubber palm pad is still solid yet removable. I cannot praise this thing enough as a stress reliever and grip strength workout tool. I don't even play guitar anymore, which is what I bought it for.10/10 still holding up, excellent tool. Cheers to the engineers.

I own a Blue (light tension) Grip Master and a Planet Waves Varigrip. Both are great and have helped my guitar fretting hand. I thought I'd give a quick summary for anyone considering purchasing one of these.I bought the Ruff Rider callus builder caps for the GM, and they really added a lot to the value I get from the GM. Calluses are critical to my being able to play well. If you are considering these, I found that it was a lot cheaper to order the Ruff Rider through Guitar Center and have them delivered for free to a local Guitar Center. I would suggest buying the actual PWV and the GM through Amazon.The PWV comes with the callus ridges on the opposing side (the palm side). So to work on your calluses you need to flip the grip over. The downside is that you can't work on finger dexterity at the same time that you are building your calluses. At first I considered this a disadvantage. However I've changed my mind and consider it a distinct advantage over the GM. There are times when you don't want to shred your calluses (show or important practice coming soon) but you still want to work your fingers. If you've put the callus builders on the GM, it takes a little time to pop them off and put them back on again, plus you run the risk of misplacing them, and removing them a number of times may loosen their fit. So I strongly prefer the PWV design for the callus option. (With the cover removed the callus builder side just harmlessly presses into your palm and you really can't feel it).I have a preference for the GM when it comes to building strength for bar type chords. This I do by holding the palm side with my thumb and running my index finger along the full set of buttons. I prefer the GM for this because it has two sets of springs in it which allow for a better and more natural (for me) squeeze.As far as exercising for finger dexterity, I much prefer the PWV for two main reasons. It's much easier (for me) to work fingers individually. It's very stable and allows me to isolate individual fingers as opposed to the GM which is kind of sloppy (too much movement) due to the double spring action which leads to unwanted movement/tilting and other fingers slipping off the buttons when trying to work a particular finger. Secondly the distance between the palm and the finger tips is about 1/4" shorter with the PWV which allows me to use better form by really curling my fingers and bringing my fingertips in from the very top. I have big hands and still prefer the PWV. If my hands were smaller I would prefer the PWV that much more.The PMV also allows the tension on each finger to be adjusted individually. For me this isn't as big an advantage as the two previously mentioned because increasing resistance is not important to me. A disadvantage of the PMV is that after about 2 weeks it started squeaking which was a bummer for my wife and kids on a one week vacation when I didn't have my guitar handy and wanted to keep me fingers in shape. "Dad - enough already with that finger gadget". However this problem is easily fixed by an occasional shot of Triflo or any silicon spray (I don't recommend WD40). I recommend spraying while the fingers are depressed then wiping with a napkin.For me, finger strength is not as important as finger coordination and speed. I seldom press the buttons all the way down, and I seldom press all the buttons together. I slowly increase speed with partial pushes and various patterns that demand varying degrees of coordination (1234, 4321, 1324, 121314, 1414, 1313, etc.)If I had to pick one or the other I would choose the PWV without hesitation, but that is just my personal opinion. If you can afford both, I would do that and see what works better for you. But, again, both are great and have really helped my playing.Keep on pickin'-Mike

The hand grips are of good quality, they operate very smoothly, and are on par with the ones at physical therapy.

Good quality and as described.

if tou need it get it
