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

Good little tool. You can use it to develop strength in you fingers which will improve your grip & dexterity. A lot of other hand grips, do not focus on you ring or pinky fingers (I also have a NordicTrack adjustable hand grip that I use for overall hand grip too - I like that one too). This little grip Master is light and portable so you can pack it with you anywhere, even a pocket. I find that it is better than a stress ball, it releases tension fairly well. Note you can use this to increase the strength for overall grip (focused on individual finger motion) or finger tip pressure (guitar, typing, or other finger pressing activities). For overall maximum grip strength I use the other adjustable hand grip... Hence I use this in conjunction with a strength developing one.I play the guitar too, I know that my overall chord playing has increased immensely. Also with the increase dexterity, I am now able to more quickly move my fingers across the frets.I've been using the medium tension for years now, and I still find it useful and challenging. Maybe in the future I will upgrade to a higher tension, but I still find the medium tension works for me.

I recently purchased the 9lb Heavy-Tension hand exerciser, not for guitar playing or any such specific purpose, but simply to build up my finger strength. Since then, I have used it pretty regularly, and it has held up to the use and abuse wonderfully. The product is well put together and feels like it can keep working for years. Moreover, I have definitely noticed an increase in my finger strength since I began using the gripmaster.The only negative aspect of it that I can think of is that I should have chosen the 7lb version. The 9lb of resistance are too heavy for my pinky or ring fingers to handle, so this makes training all my fingers evenly a challenge. However, as this is a mistake on my part and not the product's, I wholeheartedly recommend it to anyone that needs more fingers strength. I would simply recommend that buyers err on the side of caution, and buy a lower resistance version rather than a higher one.

I have small women's hands, but I rock climb, so I like to have a hand exerciser that will work the hand and forearm muscles so I can grip better on the holds when I can't get to the climbing gym. This gripper works perfectly for all parts of the finger to articulate. This spring weight (7 lb) is almost too soft in my opinion, even with fingertip gripping, but I climb frequently so maybe my hands are stronger than most?The palm grip on the version I received is much flatter than what is pictured, with just a small inward curve toward the one end and a flat grip the rest of the length (rather than curved outward like the product photo).

இ Fuzzy Wuzzy's Summary:ѾѾѾѾѾ Highly recommended with warm fuzzies!I purchased several of these black-colored heavy-tension and red-colored medium-tension GripMaster hand exercisers from Amazon in 2005, and since I have religiously used the GripMaster every day since 2004 as part of my pre-typing or pre-guitar-playing finger warm-up routines, I thought that I should add to the pile of 5-star raves. I originally bought a heavy-tension GripMaster from a local guitar store in 2004 to help improve my finger strength, coordination, dexterity, agility, and accuracy while playing steel-string acoustic guitar. But I quickly realized that by performing a variety of finger and hand exercises using this simple device, both following the instructions in the included pamphlet and adding my own exercises, my typing speed and accuracy also improved, and I could type for far longer periods of time without any hand fatigue. So since 2004, I use my GripMaster every day, even if I do not plan on playing guitar or typing for that day, to help maintain the fitness level in my hand and forearm muscles. This hand exerciser also will improve your hand strength for a multitude of sports.If you are an avid gardener, computer user, construction worker, assembly-line worker, musician, or are frequently involved in arts and crafts or other activities that involve repetitive motions with your hands, you are at risk of slowly acquiring repetitive strain injuries or stiffness in your hand and fingers because those kind of activities require repetitive motions and prolonged tension in your hand muscles (e.g. holding a shovel, golf club, paint brush, or tool in your hand for long periods of time and making repetitive motions). This hand exerciser will loosen and strengthen your hand muscles if you warm up your hands with GripMaster exercises before you engage in those activities, and also work out the tightness in your hand muscles using the GripMaster after you have finished those activities.I like this GripMaster so much that I even pack it into my luggage whenever I go on vacation. Some hand exercisers are too bulky while the GripMaster is very compact and easy to bring along during travels. And unlike the V-shaped hand grip exercisers that are commonly sold, the GripMaster helps to work out individual finger joints and muscles.If you play steel-string acoustic guitar, you should skip the yellow X-Light Tension and blue Light Tension model, and go straight for the red Medium Tension (better) or black Heavy Tension (best) model. This will immensely improve your guitar playing skills, both in accuracy and speed.So why did I buy several of both the black-colored heavy-tension and red-colored medium-tension GripMaster hand exercisers? I like to give them as gifts because I often find that both avid outdoorsy athletes and health-conscious people alike do not realize the benefits of exercising your hands/forearms along with the other parts of your body.

So I originally purchased :http://www.amazon.com/gp/product/B000UMFT22/ref=oh_details_o03_s02_i00?ie=UTF8&psc=1And I liked it so much, but decided I wanted a little more resistance in it, so I found this model made by Prohands as well, and this was listed as heavy tension, compared to my current medium tension unit.Upon arrival, not only it is smaller than the 1st one, it is a joke tension wise compared to my medium tension unit!Only differences I can tell between the 2 units units besides size are the sizes of the springs and the medium unit has "PRO" on it.

I have mixed feelings about this product, I do not have big hands, but I find it too small/thin, which makes it uncomfortable, in addition, I think it breaks in too quick, I bought the black/heavy tension, first day it was great, hard to do 30-40 rep sets, by the third day, I could handle it without problems, I doubt I got strong so quick, it takes a few days, not literally 2 days!In any case, that is why I am not giving it a low or high rating, just in the middle, i recon it does somehow helps in strengthening your fingers and forearm.
