NSD Power Essential Spinner Gyro Hand Grip Strengthener Wrist Forearm Exerciser

Really effective and good value for money. Quiet and much easier to get started than my previous one.

Got this for my husband to strengthen his wrist, works well

Spot on! Graft and hard to hold on to, but that is the point.

UPDATE AS OF 8/26/2013 at the bottom of review.. I bought this device to re-strenghten my hands after neurosurgery. Previous to my surgery, I worked with my hands(mechanical) quite a lot, did indoor rock climbing, previous weight lifting and in general use my hands quite a bit, so I think I can accurately describe whether or not this is a good workout. I would say after surgery I lost about 75 percent of my strength. I used this for a month or two, and my grip strenght steadily increased, as well as my forearm tone. I can't give you an accurate number on how much grip strenght I regained in pounds of force, but I can tell you my grip is pretty much back to normal. I stopped using this device months ago, but noticed what I thought was hand weakness again, so I started using it again. I can tell you the improvements happen right away from day to day, and if you do too much, your fingers, hands and forearms will definitly burn. This device works. Ease of use: I can tell you some people have a real hard time with this. You have to match the rythem of the device and spool up the Gyro. Some people can't seem to learn how to do this for quite a while, but I can tell you that after you learn how, it is second nature. Durability: This is where the device looses a star. I find that after treating pretty carfully, it is getting a little less smooth to gryo up, and it is getting a little sloppy at the lower speeds. To be fair, I did drop it once. Cost: I believe for what you get, it is reasonable. Fun factor: Much more fun than any other hand exercise I had done when I was a regular weight lifter. Hand exercises are generally pretty boring. You can't see results in your hands, and unless you have a weakness preventing you from doing something, you won't notice. This however, is fairly fun, and quick to do. UPDATE: This device has helped me regain 100% of my grip strenght. The nerves healed sure, but this also worked in conjuction with the healing process. The effected nerves were in my cervical spine, which don't heal like peripheral nerves do, so it is quite inspiring that I got no only my grip strenght back, but maybe a little more. I can crush peoples hands now, and I have kind of thin, "piano" fingers. I have never had problems with my grip, but I am not someone who others would think would have a "strong grip". Before using this device, after surgery, I could squeeze someones hand, and they would say "seriously, are you really squeezing?" Not that I go around doing that, but I have asked my good friends to let me re-test my grip strenght on them. I would like to buy a hand Dynamometer, just to see how far I can go. The results are inspring, and like I said above, it really isn't boring to do.

These are great hand exercisers. The work out the hand, fingers and wrist. They are actually fun to use. I went with the string pull version (drastically cheaper) to see if I would like it or even use it. The string pull is straight forward and gets the unit spinning well enough.

Compré este producto porque quería mejorar el agarre del manubrio de mi bicicleta de montaña, si funciona, con usarlo unos minutos al día he notado que puedo rodar por más tiempo, sin molestias en muñeca y antebrazo, como me pasaba antes, el paquete llegó a tiempo y el producto es de buena calidad.

I honestly cannot say enough good things about this! I love it! For as simple of a design as this thing is, it is an amazing developmental tool to have. I use it partly for my bodybuilding purposes, and partly for my fighting attributes training, making it a point to use it daily. The learning curve for using it is not as steep as others may suggest (at least it was not for me; rhythm to match the spin was established in a matter of seconds on my first try), and it only gets easier from there. I have gone on so far as to develop a total of four movement patterns for my training sessions, to get the most complete use of the spinner. Looking for a different, and effective way to train? This is the way to go!

It's so easy to start and we'll worth the money. I would certainly buy one of these again if required
