      Comments about Dyna-Flex Lighted Gyro Power Ball:

      This product is very hard to "start". When I eventually got the string to start the Gyro after only four pulls the string got jamed inside the mechanism. Great idea but it should include a "starter" which is "sold separtely". Hopefully they will quit trying to sell add ons and just include the starter.

      Good Luck

      Comments about Dyna-Flex Lighted Gyro Power Ball:

      I was skeptical of this little ball upon first glance. I've used the stereotypical squeeze toys for hand strength, and have found they do give a good pump after a while. I bought this on an impulse and can say I'm happy I did.

      Not only does this gizmo work your forearm and hand strength, but depending on how you hold it you can also work you triceps, biceps, and shoulder muscles. Also you can vary the intensity but increasing or decreasing the speed.

      I will say that it is difficult to start without the string at first. However, you can start it without the string but flicking the little rotor with your thumb. If you lost your sting or didn't recieve one like I did, you can use a small round shoe lace (think dress shoe) to start the rotor. It takes some practice to manipulate the rotor speed, but once you understand how to move your hand it's prety easy afterwards. It took me about 10mins of tinkering.

      Overall it's a durable and relatively cheap training tool that can be used almost anywhere. One more note, it does produce a noticeable buzz when it's up at speed, but nothing obnoxious. Check out tha manufacture website for tutorials if you're having trouble.

      Comments about Dyna-Flex Lighted Gyro Power Ball:

      highly addictive... once you start you dont want to stop, good warm up for tougher activities... and also you cant really start it unless u have the string or the starter... that flicking technique doesn't really work or im not doing it right.also the rubber on the sides starts to chafe away at the fingers. (proly because I use it for about an hour each time)

        • Frisbee
        • Golf
        • Mountaineering
        • Typing

        Comments about Dyna-Flex Lighted Gyro Power Ball:

        This is by far the best hand, wrist, and forearm work out on the planet and there's the added bonus of being FUN! As you twist it faster and faster, the unit turns faster and thus puts more gyroscopic inertia in your hand forcing you to hold on tighter. You can use it while watching TV, movies, walking and its great fun at parties!

          Comments about Dyna-Flex Lighted Gyro Power Ball:

          This works really well to build and condition your forearms and grip. After even a few minutes of using it you can start to feel a burn. It is a little hard to start without the string at first, but after using it for awhile, you quickly find easy ways of getting it going. The price is a little expensive, but I feel that it is definitely worth it for what you get out of it!

          Comments about Dyna-Flex Lighted Gyro Power Ball:

          This is an excellent forearm strengthening device. For everyone who says otherwise, your doing it wrong. If you get full rotation of the wrist (flexing back is the hardest part) 5 minutes seems like torture. I keep it in my car and use it when driving to work. It is somewhat hard to start without the string but if you run it on your pant leg it is doable. I used to have one of those stress balls but it popped and poppy seeds went everywhere. Overall, excellent product.
