Prohands PRO Hand Exerciser, Finger Exerciser (Hand Grip Strengthener), Spring-Loaded, Finger-Piston System, Isolate and Exercise Each Finger

I started out with the grip master light tension. This was too much resistance for my little finger, so I bought the grip master extralight tension. The combination of these two units allowed me to gradually strengthen my fingers to the point that I was ready for the medium tension (seven pounds resistance). I decided I would buy the more expensive grip master PRO unit with seven pounds resistance. I like it, but I'm not sure it's preferable to the slightly less expensive REGULAR grip master unit. The rubber surface on the buttons is easier on my fingertips, but because the buttons are convex rather than concave, my fingers tend to slide off the buttons more than on the regular grip master, which has concave but non-rubber buttons. Both units seem reasonably durable, and they are inexpensive enough from Amazon that if I ever wear one of them out, I can buy another one with no problem. This is a great way to strengthen your fingers, and it has improved my ability to play the piano and the guitar significantly within about six weeks of use. I keep the units in my briefcase and use them when I am reading something at work. This does not interfere with my reading, and it allows me to give my fingers a good workout. It has also improved my speed and control typing on a computer keyboard. I'm not sure which is preferable - the regular grip master or the grip master pro. I think you would probably be happy with either one. I do like the shape of the rubber surface that presses against the palm of my hand better on the grip master pro than on the regular grip master. If I had to do it again, I think I would buy the regular grip master with the concave buttons. NOTE: Be sure to use this device by pushing the buttons with your fingerTIPS, not the flat part of your fingers. You will not be able to handle as much resistance this way, but it will strengthen your fingers in a different way, and in a way that is important to playing a musical instrument.

This is an amazing product, I started out using the light version a few years ago, and now I have upgraded my way to the heavy version. This is about 10X better than the non-pro version of the gripmaster, it fits the palm better, has more even resistance, and most importantly, isnt squeaky and annoying. I started using these to build up my grip strength for weightlifting since most weights I was lifting fatigued my forearms and fingers faster than the muscle I would be training. Now, I don't have that issue anymore, in fact, my forearms and hands are probably the most developed and rock solid muscles I have on my body. This thing seriously works, and fast. There are also some programs you can look up on the internet to find different ways to train individual muscles in your forearms and hands. This works great before workouts to get your hands ready for stabilizing heavy weight, and I even use it like a stress ball sometimes. I usually throw it in my pocket and use it on long drives or bored in the waiting room or something like that. Hands down probably one of my favorite amazon purchases, amazing price and quality for how much use it gets. don't second guess yourself, just buy one already.

It's really nice, small form factor, works out the muscles well. Just 2 cons on this device: 1- All the springs are the same tension. That means the max tension of this device is not 4x9LBS, but 3x9LBS, as the 3 bottom springs bottom out before the 4 top ones do. It also means your pinky has a much harder time to work out than your index, or middle finger. When you buy the light version of this, is great for pinky, but lousy for index/middle/ring finger. The red (medium tension) gripper is good for the ring finger, but somewhat basic for index and middle finger, and hard for pinky. in other words, if you're like me, you'll have to buy several to train a hand. 2- The bottom springs are pretty useless. They actually tilt the device when training individual fingers. The company also sells a mid, and a basic version of this device (this is the Pro device). The mid device and the pro device both have the same issue. When the device tilts, it tends to slip out of the hand. The basic version does not have this bottom spring set; and feels more stable in the hand, but doesn't have the higher resistance tension... 3- The bottom rubber doesn't feel very stable in the hand. It's very narrow, and sometimes tends to slide in the hand (esp when sweaty). The top has 4 buttons covered with rubber. It feels nicer than the mid-quality brothers for the medium tension (9LBS) or up. If you want to go for light, consider the basic, or mid-quality grippers, as they are a few $ cheaper, and quality wise make very little difference. Aside from these quirks, these grippers are very good. I bought 3 sets, but for a regular male, I would recommend starting out with the red version (medium strength). If you do regular workouts, are athletic built, consider skipping the regular, and head for heavy, or x heavy!

Pro medium tension. Good level for improving finger strength for brass instrument playing. DSolidly built. Comfortable to use.

I ordered the Gripmaster Pro to improve my fretting hand strength. I'm double-jointed on the last joint of my ring finger, and really wanted something to improve my finger stability and individual articulation on the ring and pinky fingers. I had purchased the Planet Waves Varigrip earlier, and thought it was ok. But as soon as I opened and started using the Gripmaster Pro I immediately saw and felt a difference. The build quality and materials are noticeably better. They built it better than it had to be, which is always a good sign. Don't mess around with any of the other grip strengtheners... this is the one you want! Make sure to get the Pro version, and plan on stepping up to the heavier tensions before long. The difference in my finger strength and dexterity is noticeable. I have no qualms about recommending this item. I'll be stepping up to the next tension level within the week.

This product far exceeded my expectations. I have had the product for 18 days. Four months ago, I tripped and caught myself with my hands, most of my weight was on my left hand. Unfortunately, as a 44 year old male, my fingers did not heal as quickly as I thouht they should. I was preparing to make an appt with an ortho Doctor, but, I thought I would give this product a try. My fingers were constantly in pain. I am someone who works out 3-4x each week. I can run 5 mi without stopping. I was shocked that I was in this pain just from catching myself from a fall. 1) My hand started improving within 72 hours--I'm not kidding. 2) My fingers were noticeably stronger in 1 full week. 3) The constant pain in my fingers have completely left--I thought I was enroute to surgery On a scale of 1 to 10, I was a 3 when I began using this device 18 days ago. Today, I am a solid 8. I am extremely pleased with this turnaround in only 18 days. Initially, I used the product on a daily basis. Now, I want to really get my strength back and "go hard" every other day. This will give my muscles a chance to fully heal. I fully expect to be at a "10" in the next 6-8 weeks. I thought I was enroute to the surgeon--for sure!! I bought the the med tension, which was plenty for me. I am using this on both of my hands. My left hand is getting so strong, I don't want it to pass up my right hand. Do the exercises slow. Use 1 finger at a time for max results. Maybe I will work my way into the 'heavy' next year, but I am not in a rush....I'm not 21 years old bench pressing 300 lbs any more. I'm just trying to stay healthy and away from the knife of a surgeon. So yes, buy this product and you are trying to rehabilitate your fingers. I think the xtra light would be great for a broken/fractured finger. Good luck

I have been having wrist pain during the summer from softball and golf. I am hoping that working with this machine during the winter will help strengthen my wrist and alleviate some or all of the pain. This thing is great. I can tell that it is working and I really like all of the different exercises (make sure you go to their website and read up on all of the exercises). I have graduated up to the heavy for some of the exercises so I have already purchased that one. Having two different tensions is ideal. Great little stress reliever and wrist strengthener for at the office.

Compact device, easy to bring in your pocket, helped with my stress and improved my guitar skills!

Très très bonne qualité

Tension de 3.2 kg par doigt, la difficulté à mon niveau est pour l'auriculaire, utilisation depuis plus d'1 mois, tres satisfait. Update 8.07.2013 Utilisation depuis janvier 2012 plusieurs fois par semaine par 100 reps x2 ou x3, produit qu'on peut qualifier de qualité. Grâce à lui, j'ai pu renforcer mes 2 mains ( plus aucune difficulté niveau auriculaire )et il y a peu de temps j'ai pu passer au modele supérieur de 5 kg mais je dois alterner entre les 2 pour l'instant avant de songer à me servir uniquement du modéle 5 Kg. Pour ma part, j'ai observé des douleurs aux jointures, ainsi que des rougeurs apparaissant à cause de la friction lorsque j'applique une pression avec celui de 5 kg ( notable au bout de 50 reps ), donc un conseil allez y modérément ou prenez le modele de 4 kg.

手のひらにピッタリでトレーニングに違和感がありません。

La verdad que la gente que dice que quiere ejercitar la mano, tipo ponerse fuerte la mano no sé si piensa bien o algo. Me rompí la muñeca y este producto sirve para reanimar los músculos que se han quedado paralizado todo ese tiempo. Es para reducir la probabilidad de artritis muscular. El producto es 10/10. Plástico resistente y muelles fluidos, se me ha caído al suelo más de 1000 veces y no Le ha pasado nada. Recomiendo este nivel de fuerza si antes de cualquier lesión tenías una fuerza media-fuerte. Si partidas nueves con las manos te recomiendo el negro que tiene una resistencia mayor (recuerda que tienes que ir poco a poco ganando fuerza, así que este para empezar no está mal)

Choose yours based on the pressure required.
