After owning this product I must say DO NOT BUY IT! For the same price you can buy an NSD powerball which has a REAL warranty with it. My ball broke and DynaFlex only tried to sell me a new one regardless of the warranty printed on the back. The Sports Authority felt bad enough they ended up replacing the ball free of charge while DynaFlex stated I either buy a new one or pay them to re-send my broken one back. I showed dynaflex a picture of how my unit broke BUT once they received it their opinion changed from "Axels can break when they are sped up too fast" to "the only way our axels break is to be dropped".

Here is as good as it gets, an entire post about this from the DynaFlex forum that DynaFlex removed before people could read it any further:

I just wanted to say I am bummed at this point. I tried a gyro at my friends house and loved the idea so I
bought my own. After a month it started emitting a high pitch sound at start up which would compare to a
bearing going bad and starting to squeak. A month later, today to be exact, I wrote into the company to ask
how the warranty works because the device is now having a much harder time starting and within a few hours I
hear a POP and the balls grinds to a halt. I see the ball has fallen away from the white track it lays in and think
it just fell out of it's track. Then a small piece comes out and the actual bearing inside the wheel broke. I really
like this device but if it's going to break down so quickly and a warranty has to take place often is it really
worth it in the long haul. If the white piece had broken (it looks plastic) I would understand but a metal like
piece breaking is weird right? Has anyone else experienced this? Is the NSD version any better for users who
are going to use this as regularly?

WipeOut,
I think weve been speaking over email but I'll respond here as well. We'll inspect your ball so we can determine
what exactly is going on.
Though it is extremely rare for a ball to break so suddenly, it may happen. We do offer lifetime warrantys on
manufacture defects and we are honoring that with you by going through an inspection. But if it has broken
down there could be one reason one.
Your Forearm strength is too much for the gyro
This usually happens with a lot of rock climbers and other individuals with decent forearm strength. They get
the Pro or Pro Plus and a couple months later it busts on them. Thats because the basic Pro has a MAX capacity
of 25 lbs of force, or 12,000 RPMs. 12,000 isnt that hard to do for a fit individual. It could be that you wore the
sucker down and something busted because it doesnt have as high as a capacity as the Powerball or even our
Iron Power line.
In any case, we'll take a look at it and see what happened and most likely ship you out a brand new one.
-Joey

To WipeOut97:
I haven't had that problem. My pro just has a hard time starting up and i think i had it going on a year. The
NSD powerballs are pretty good. I own two and don't have much of a problem with them.
To Admin:
The site info bumped up all the RPMs for every powerball to 15K except for the Platinum Powerball which is at
15,500. In theory all of the plastic powerballs should be able to exceed 16,000rpms without busting the ball. So
what gives one dynaflex plastic powerball a higher capacity than the other?

Dstar,
We've been changing a few things in our website and some numbers are absolutely wrong. We stick to the
number 15,000-16,000 RPMS for the powerball. The Platinum has a little bit higher capacity so it can hit higher
RPM's and force, usually around 5 lbs more.
We should have the correct figures up soon.

My WipeOut97 account appears to have been blocked from posting on this forum but oh well.
Thanks for your reply here Joe, we did talk about this and I'm glad I was able to find the receipt.
Dstar,
With your Pro do you ever hear a high pitch squeel when you start it? When the high pitch started I noticed a
quick decline in the ability to get my ball started the first time. Between the two brands which one would you
prefer? If my strength is the issue do you think the NSD would hold up any better and do you think they offer
any advantage?
Thanks

Something was going on with the forum where I had to reset it, which I have, so your other username probably
works now. The forum is relatively new so we are working out all the kinks.
In regards to questions about NSD, both Dynaflex and NSD are very well made products and they likely have
the same amount of random defects we do. Key difference is they are in Ireland and we are in the US. Also,
Dynaflex is the original, we have been around since 1977 I believe.

In case anyone is wondering about my outcome. I spoke with Joe for a few days and DynaFlex has denied my
warranty based on their idea I dropped the ball. I posted a picture here prior to sending the unit in but once
the unit was received the story changed to: "The only way an axle breaks is in a ball drop". Well if that is the
case why did they not say the warranty was automatically denied? Instead I shipped them a ball and paid
roughly $4 to ship it to them. After being received Joe has only been trying to sell me more balls at a price
point to where it is a couple dollars below retail price. I have to now pay them to ship back my broken ball so I
can ship it to the sports authority where they are allegedly going to replace the ball for me.
Joe, you answered the differences between NSD and your company. What you have to take into account is NSD
has a lifetime warranty that goes beyond what you "deem" to be abuse of a product. They will repair any partof the device and ship it back at their cost regardless of what they feel happened. Your price point and NSD is
almost the same so I don't see how your products equal theirs. To me I feel dynaflex has a warranty written on
paper and that's it. I found a few people on the NSD boards with similar experiences of sending a ball in only to
be hit with a "I'll do you a favor and sell you another one" approach.
In the end I spent:
$22.99 dynaflex pro
$3.89 shipping to dynaflex (2 months after purchase)
$5 to mail a label to dynaflex for them to ship it back
$3.89 to ship it to sports authority
total of: $35.77
NSD with full lifetime warranty is: $32 shipped
Dynaflex offered (under their replacement plan):
another 14.95 for the gyro pro
16.95 for gyro +
18.95 for amber light up
Conclusion:
Buy from a company who backs their products such as NSD and stop trying to sell more products to customers
who are attempting to get warranty work done. As I said, why would anyone spend another dime with a
company after they have had issues with their current product? It simply makes no sense from a practical
standpoint.

I recently purchased a dyna-flex gyro powerball from Amazon. Prior to purchasing it, I did get a chance to try it out at a local BIG-5 store. They had a powerball and the docking station for display and use to customers right in front of their cash register. I tried it out and all of my skepticism quickly went away. Let me tell you, I have a ton of joint issues from weight lifting like wrist tendonitis, tennis elbow (barbell curls) and rotator cuff soreness (bench press). My first impression was how much torque this little thing produces. It was as if the ball was trying to free itself from my grasp but when I held it and rotated my wrist, it helped created enough tension where my muscles were being put into play. I ended up not purchasing the item but when I drove home I suddenly realized that my wrist felt better and my natural range of motion in my wrist was coming back whereas before I couldn't without some sort of soreness or tightness in my wrist.

After looking at other great reviews online I decided to give it a shot and bought it off Amazon. Every day I'd do a variety of arm motions with the powerball gyro spinning in my hand and after about a week my tennis elbow pain decreased dramatically, my rotator cuff was healed but what felt the best was my wrist having its range of motion back. Lifting weights at the gym requires my wrist to be strong and able to withstand jerking movements and ever since I have owned the powerball, my wrist never felt better. I highly recommend this product not just as a rehab tool but to prevent injuries in the future by strengthening the muscles that the powerball emphasizes. Bravo DFX, you have created a product that not only looks cool when it lights up, but single handedly reduced my injuries.

I bought this and it worked wonderfully well at first, the grip is very good and it exerts a lot of force for beginners like me. Unfortunately it stopped working after a 4 ft drop onto a hard floor, I know this is my fault, however I wish the product would resist this.

Overall good buy but DO NOT DROP IT.

I love this little thing... takes a little time to be able to start it up without the string, but is definitely doable and everyone that's tried mine has eventually been able to start it on their own.
Great item so far. It's had plenty of use in the weeks since I bought it.

I had a Carpal Tunnel syndrome. I used it for 15 days 3 minutes a day and get well. Very happy!

So I got this a couple of days ago. After opening it, I wasn't able to get it started, but that was due to lack of experience. My friend was able to start it since he has another gyro of his own. He said it felt a little rigid, but it worked fine nonetheless. After maybe 10 successful tries to start it and maybe 30 failed attempts, the thing just got jammed.. It still spins, but VERY slowly. Like after pulling the string, it stops within a second or so on its own.

This is the second or third I have had around. Very helpful in alleviating, and preventing - wrist, arm, or hand pain.

This is a great little device for strengthening your hands, wrists and arms. It starts spinning easily with the dock and is very easy to control. I suggest that you watch the included DVD and/or go online to learn the proper way to use the Exerciser. Although I didn't need rehabilitation for carpal tunnel or any other ailment, I use the device for building up my muscles and after a few weeks the results are there! I now have more definition in my forearms, biceps and triceps thanks to the Exerciser.

I was told about this item from a friend. I went to Big 5 Sporting Goods and bought one.
It did NOT come with a cd to explain how to use it. I could not get it to work because of that lack of instruction. I returned it.

A couple of months later he told me about the battery operated starter, so I got another one, but from Amazon, and got the power starter.

I LOVE this device now. It came with the info disc. Yeah !!

I have used it once a day for a week. About 30 min each time. I switch it from hand to hand, as my forearms get tired.

Seriously....I FEEL the strength in my arms, shoulders, and hands returning. You see, I have a bad back, so lifting weights and 'working out' causes pain in my back that can last several days. This device is giving me my life back, a little at a time.

I went camping for 5 days with my 15 yr old G-child over T-day wknd. We took turns using it, then handing it off to each other. Once you get it spinning, you can keep it going forever.

I use it while watching TV, reading, and web-surfing.

I had one of these maybe thirty years ago. Bought another one last month. It is still just as cool as ever. If you know a golfer, climber, or anybody who needs strong hands and forearms, this thing will put a grin on their face and also draw a crowd if you show it around at work.

Don't however use it for carpal tunnel and such without consulting a medical professional about your individual condition. Exercise like this can build muscle but the extra muscle can cause more internal compression in the wrist, which is maybe the opposite of what you want. Same for tendonitis - putting more stress on tendons (which this definitely does) can build tendons or hurt them.
