DynaMax Pro Trainer 12086PC Core Strengthening System Review

Average Reviews:

(More customer reviews)I got this for Christmas this year and was very excited as I have the smaller version and it has been a great tool for years. I began using it right away and have used it every day with a noticable improvement in arm definition. Unfortunately when I picked it up today and pressed the button on the end to get it started it made a terrible rattling sound and failed to spin up properly. It appears that the rubber wheel on the little motor that spins the gyro up to speed has shifted and is no longer contacting the inner surface properly. I have contacted the company for service/replacement. I will revise my rating depending on the service I get. Stay Tuned!
*Update*
Well I called the company and they seemed more interested in not being responsible for the repair then being helpful with the return/information relating to the problem. I'm guessing this design is not working so well for them as they are apparently making a new version that is manual start (like the smaller hand version). I'm guessing that the little electric start up motor/mounting is not up to the vibrations this creates during use. I'm plan to wait till the new version comes out and getting on of those.
*UPDATE*
New manual start version is finally out!

Smaller and lighter than the DynaMax Core Trainer, the DynaMax Pro offers the same high-end functionality but for a more affordable price. The DynaMax Pro is designed with the same principles in mind as the company's handheld gyros, but with a focus on working your core and upper body through resistance and isometrics, rather than just your arms and elbows. The gyro is distinguished by a built-in starter and LED lights that get brighter as the speed increases. More importantly, the DynaMax Pro generates roughly 178 pounds of resistance and a top speed of 6,000 rpm, helping the user maintain balance, speed, and endurance--all essential for core training.
The DynaMax Pro Trainer is made of machine-molded, high-strength plastic, which provides a super-strong housing while lessening the cost per unit. The material translates to a very affordable yet cutting-edge training device. Each unit is also inspected and tested by the company's expert craftsmen, who take pride in knowing that each Pro Trainer is the most effective and unique training tool available. Other features include a built-in starter, foam rubber grips, and an instructional training DVD. The DynaMax Pro requires two AA batteries (not included).

DynaFlex Docking Station with Amber Powerball 12080 Strengthening System Review

Average Reviews:

(More customer reviews)This little ball is fantastic. It provides quite a workout for my forearms, and I actually get a workout because it's fun to use. I know that the novelty will wear off eventually, but I can't stop using it at the moment. Even though my arms are tired, I still find myself spooling it up for another go! It's difficult to convey, but it truly is tiring after about a minute, at which point I need to switch arms (although I'm sure that I'll build up stamina). It's a good feeling, though, and let's me know that I'm working out my arms.
It does take a little while to get the hang of starting it, at least for me and those that I've talked to. In fact, I thought that mine was defective when I first tried it. If you have trouble, just give it a little time. The key for me was to get it going past a critical speed at which point I could get in a rhythm with it and speed it up. The starter string works very well for me (I'd like to point out that there are three holes that the string will fit into, two of which have LEDs at the bottom, so use the hole that doesn't have the LEDs). The docking station hasn't worked for me at all, though. Before the ball gets spooled up, the gyro turns it off center so that the spinner in the base actually causes the ball to stop. Kind of a waste for me, seeing as how well the string works. It also only took about a day to get good enough to start it without the string by just using my hand.
I would like to point something out that I missed when I was making my purchase. Despite the "Product Features" listed for this (amber) version and the blue version being identical at the time that I'm writing this, the blue version is actually capable of higher RPMs (18k versus 13k) and more torque (40 lbs instead of 35 lbs). They are described correctly further down on the page, but I didn't notice it there. I thought that I was simply choosing between two colors and not actually getting a less capable Powerball. Add in that the blue version is currently cheaper, and I would have gone with the blue one. I wanted to point that out in case anyone else focused on the top feature listings and missed those two numbers being different in the detailed write-ups.
Despite the base not working for me and the small amount of regret in not getting the blue version, I am extremely happy with this product. I really do consider it fun to use, the lights on it look cool when it's spinning, it even sounds cool when it starts to rev up, and it is more of a workout than I had anticipated. I highly recommend giving one a try, but consider getting the blue version without the base (if it's cheaper without the base).

Power Ball Pro Gyro - The Gyroscopic Exerciser That is Capable of Speeds over 9,000 rmp and 25 lbs. of Torque Review

Average Reviews:

(More customer reviews)This little gyroscope is a great forearm and wrist trainer, but only if used in addition to a "wrist roller." Wrist Roller This will initially feel like it is a good workout, but you will strengthen these small muscles very quickly. After about a week, you should be using this AFTER you have fatigues your forearm and wrist muscles with a different exercise. (Again, I recommend using a wrist roller the most.) If you do this, you will see the largest results, and develop much stronger wrist and forearm muscles.

DynaFlex Docking Station with Blue Powerball 12075 Strengthening System Review

Average Reviews:

(More customer reviews)After reading some of these reviews, I was worried. I inserted the batteries, inserted the powerball into the docking station and held it down while pressing the button. It barely spun as it started turning sideways. I was thinking the negative reviews were correct or mine was broken. Then, I noticed the picture showed it not being held down when in the dock. So, I aligned it, let go of it, and pressed the button. It immediately spun up to a high speed and I picked it up.
The 1st time I tried it, it slowed down. Again, I was thinking the negative reviews were correct. But, I went to their site and watched their video. Once I realized that the written instructions (which say left to right motion) are wrong, it was easy. You rotate your wrist in a simple circle (like you are drawing a small circle with a pen). When you do this and it is spinning fast enough, you suddenly feel it "catch" and start speeding up. If you circle too fast or to slow you can feel the change in resistance and stops increasing the speed. So, by circling at the speed that gives a constant pressure back, it gets faster and faster (you can hear it revving up). I found that I could learn the motion with bigger circles, but the big speed up happens with smaller circles.
I then tried the string start and it works, but you have to pull really fast. Pulling hard is useless, pulling fast is what is needed (it has no real resistance).
I have not tried a thumb start, but I can see how it would work - you need to have the circling motion just right though (cannot take long to catch the right speed).
I have only had one day, so cannot comment on how well it helps my wrist pain (computer use). But, it does feel like it will strengthen my wrist, which is what I need.

Dynaflex Powerball Gyro Wrist and Forearm Exerciser Review

Average Reviews:

(More customer reviews)This item is a great item that is fun and works out your arms so great that it feels like they will fall off. Although when i bought the item i thought that i was buying the highest end gyro ,Powerball Blue, with speeds of up to 18000rpm and 40lbs resistance. This is simply a cheaper gyro that they applied blue lights to and called the powerball blue since it only has 32-35 lbs resistance and speeds up to 13000rpm. So make sure you know what you are buying because it was a big mistake for me

Dynaflex Sports Pro Plus Gyro Wrist Exerciser Review

Average Reviews:

(More customer reviews)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.
