NSD Power Essential Spinner Gyro Hand Grip Strengthener Wrist Forearm Exerciser

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.

Great product. Simple and efficient.

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
