250Hz Gyroscope - Grip, Wrist and Forearm Strengthener for Sports and Rehabilitation (Classic)

When you first open the packaging, You will see a Powerball and 2 pieces of red string- cord.. 1, At first, I thought the Powerball was a bit of waste of time. It took me a long time to get to grips with how you get the inner ball to rotate. Once you have the hang of it though, it's really quite easy to use. 2, Place the small length of red cord into a hole and turn the inner ball a few turns, Then pull. It will start to spin slowly. The idea is you then turn your hand and slowly to keep it rotating. It is the inner ball which spins. Then the more you turn your hand the faster it will. And the harder you have to hold it, That is the idea of it. 3, This is the original Powerball and I think the best, The manufacturer's description really doesn't do this product justice, Try the website. very helpful site. 4, First use this Powerball at low speeds it is great for wrist and arms. At the high speeds it gives an Amazing workout and really builds up all the arm and shoulder muscles. That is If you can hold on to the ball, it is quite hard at full speed. I think it would benefit Racket plays etc. 5, The build Quality is Excellent and there is a lifetime guarantee. I could write so much more about this product, If you want a great workout for arms wrist and shoulder, Will leaves your arms etc. burning after a few minutes. You've got to buy one and try for yourself, you will not regret it. This one has lasted me a long, And still works great. You could Try the version with a Timing computer on top of the Powerball so you can see how you're progressing. I would Highly recommended great workout. Well worth the money for a Quality Powerball.

Ok, the story goes - Muppet here broke her wrist so spent 4 weeks in plaster - Once out of plaster, my physio recommended squeezing a ball and to make sure I used the wrist to gain flexibility. Yup, I squeeze the ball! but use the power ball for the flexibility bit. Easy or what? Can not thank this ball enough for the movement I now have back in my wrist just 2 weeks after getting the plaster off. So easy to use and flexes my writs just the right amount without hurting, allows me to build on the rotations, so I now have full movement. Brilliant piece of kit. One that I will be using regularly to keep my wrists and arms in good shape. As for the price, I would say excellent value as it does what it says on the box. Very satisfied customer.

This is a good hand/physio aid to strengthen the wrist/arm and hand. As long as you can get it to spin! When I first got it, I could do it. At the moment, I can't. I'll persevere as I'm a patient person, but if you're not so patient, it may be an issue. When I got it working, I could definitely feel the resistance so it can do as the product description says.

If you can't get the ball to spin it's your technique not the ball! Once you master that the Ball will be great fun And Will definitely improve your grip and strength it's good quality for the price And seem to be well made, I've just started trials riding and use it to improve my wrist strength And to relax the wrists after a strenuous ride

I've had this for a day and I am not very impressed by this product. Firstly it's not all easy to learn how to use it. I wouldn't expect a several-pound product to be manufactured as smooth and balanced as described but it loses momentum a bit too easily especially when it's not spinning fast enough. I spent a few hours on it yet still have trouble getting it going with my non-dominant hand. Secondly it's not that much fun. I don't quite get it why it's 'addictive' or whatsoever. I imagine even with a rpm count, it wouldn't be any sort of 'great fun' just to get it spin crazily fast. If you go check out the videos on youtube about people making it to 18k or even 20k rpm, the guys had to shake their hands as if they were getting an electric shock. I simply don't see any fun there. After all it's just a fairly good toy. Very good concept, very suitable for physics teachers' demonstration regarding gyro force. Surely you'll have a few pound worth of fun and that's about it. Not amazing.

As I've only had this for a couple of weeks, time will tell how effective it is. It seems well made and sturdy, comfortable in hand and you feel the Gyro as you work against it. It took me a good few attempts before suddenly I was successful, but longer with my other hand. Strange that as my dominant hand took longer to master it. I find it spins in both clockwise and anti direction too which you can change while it is spinning. The trick I find is to rotate smoothly as any jerky movements affect it spinning. I'm not sure if it is successful yet but I can feel the muscles after a few minutes use, they are aware of being used but not in a painful way. At the moment I use it around twice a day for around two minute seach hand. No doubt I will build this up for longer sessions in future. Please ensure you use the wrist loop though. I think if it got loose it could do some damage. I have not tried that but there is quite an energy build up as the Powerball rotates. I bought this to improve my grip and tone up my forearms etc. I am 80 yearsold and find my muscles not as firm as I would like. New update. A couple of weeks in and going well. I can feel a difference both in grip and firmness of forearms. I am up to 5 minutes each arm twice a day and can not only change direction of spin, but swap from one hand to the other and swap the wrist loop as wellwhile itspins. I am pleased with this product and will keep at it. I wonder if the "NO Pain No Gain" is necessary, as apart from a bit of tiredness and a not unpleasant feeling that Ihave used my muscles, there is no pain at all. I am happy about that as I am not a pain lover.

Unfortunately within 20 mins of getting this it is broken. I did get it spinning pretty fast a few times but I then made an attempt pulling the chord down fast it ripped the ball out of my other hand such that the ball fell to the floor quite hard (kitchen tiles). I then spent half hour getting the tangled up chord back out again but unfortunately the internal mechanism no longer spins freely. Admittedly this is user error on my part but annoying it’s not a little more robust.

My son has his own gyroscope, and I find that very hard to handle. This one is ideal for an elderly woman's wrists. Really good.

Causa una brutta epicondilite ho acquistato la rpm power se vogliamo anche con poca fiducia. Seppur da pochi giorni che la uso ho notato un buon miglioramento soprattutto nella aumento della forza dei muscoli avambraccio. Naturalmente è solo un piccolo passo ma in questo tipo di patologie se non si vuole incorrere in infiltrazioni ci vuole tanta pazienza ed esercizi giusti e la powerball è un valido alleato. Sinceramente non capisco le difficoltà di molti utenti nel farla funzionare . Personalmente al primo colpo sono riuscito a farla partire....incuriosito ho fatto provare ad altri amici e nessuno ha avuto problemi. Se posso permettermi seguite queste semplici istruzioni: 1) arrotolate bene il cordino rosso nella scanalatura del rotore 2) lasciate circa 5 cm del cordino penzolare verso il basso. 3) afferrate la sfera con la vs mano dominante e con l altra tirate con forza verso il basso perpendicolarmente 4) il rotore entra in funzione a questo punto con il braccio FERMO ruotate il polso con dell circonduzioni e assecondate il rotore e vedrete che non ci saranno problemi.AVVERTENZE: attenzione le prime volte soprattutto a non esagerare sia con il tempo (min 1 max 2 minuti)che con la rotazione perche piu gira piu simula un maggiore peso fino ad arrivare a oltre 20kg. Conclusione se avete problemi fisici ai tendini/muscoli usate una bassa rotazione se invece volete fare lavoro di potenziamento muscolatura usatelo a giri superiori

It works as expected, no complaints, came with two strings to start it so that's great!

It is little pricey but does the job it says

I tore my wrist ligaments and my doctor recommended that product to me so i ordered it. At the beginning i was a little bit confused how it might work, but after a few times of trying i finally figured it out and since then it became a common practice for me. I’d recommend you to buy if if you want to strengthen your arms.

No lo conocía, lo compré por la opinión de otras personas para recuperación de muñeca. Ha sido un descubrimiento. Te permite ganar fuerza y mejorar el giro de muñeca sin coger pesos . Es un invento extraordinario. A mí me dolía la muñeca y no podía hacer flexiones o ejercicios en los que tuviera que cargar mi peso sobre la muñeca. Incluso coger una bolsa con algo de compra. Después de usarla de vez en cuando fui recuperando sin darme cuenta. Estoy muy contenta porque ya puedo coger pesos, ha pasado más rápido de lo que esperaba. Aprendí su funcionamiento en video de Youtube, (hay muchos) porque las instrucciones que trae no valen para nada. Es de un material que parece frágil siempre tengo miedo de que se me caiga y de rompa, aunque no ha sido así. ( Se me ha caído un par de veces). Funciona bien y el arranque del giroscopio es con cordón. He cogido el truco enseguida.pero reconozco que de joven hacia natación sincronizada donde ese giro de muñeca se usaba mucho , a los que se lo he enseñado les ha costado bastante más aprender a usarlo ( pero se consigue).
