NSD Amber Regular Screamer Powerball

The powerball 250ghz gyro is a great exercise tool for strengthening, toning or rehabilitating your wrist, forearms, upper arm and shoulder. The gyroscopic motion is solely decided by yourself so you can choose whether to do slow rehabilitation excercises after an injury or a muslce pumping workout with speeds of 16000rpm and higher.

When using mine for a long period of time, I have found that it really has pumped my forearm muscles, however- the motion can cause the outer casing to rub on your fingers which are like small blisters but this is down to the way you hold it and in general, the ball is quite comfy in your hand. ... more

The powerball 250ghz gyro is a great exercise tool for strengthening, toning or rehabilitating your wrist, forearms, upper arm and shoulder. The gyroscopic motion is solely decided by yourself so you can choose whether to do slow rehabilitation excercises after an injury or a muslce pumping workout with speeds of 16000rpm and higher.

The high force of the gyro really causes the ball to sling some momentum from side to side so you really need to grip it hard or else you will drop it which is one of the rules not to do as the heavy motor damages the casing which is a little inconvenient considering it tends to squirm uncontrollably. When using mine for a long period of time, I have found that it really has pumped my forearm muscles, however- the motion can cause the outer casing to rub on your fingers which are like small blisters but this is down to the way you hold it and in general, the ball is quite comfy in your hand. One other downside is that the ball is quite loud, as the gyroscope spins, it creates a high frequency whilstling sound which can replicate a muffled drill sound if you have some speed going, however, behind a closed door- I believe the sound isn't a problem, i just wouldn't recommend it on a 5 hour train journey or the such.

I bought the additional speedometer that can be added to the top of your gyro, this is recommended by myself as this is the incentive for you to continue using it as it stores your maximum amount of revolutions, records your strength and more which is great with mates when they cannot beat your amazing score.

Some people claim that they find it really hard to get used to, this is nonsense if you have at least 1 brain cell. Using the starter cord provided, you pull it sharply to begin the gyro motion. Gently rotating your wrist the gyro picks up speed depending on how fast you rotate your wrist so you determine the speed.

Overall, I give the powerball a 9 out of 10 as it is a convenient and practicle workout in the palm of your hand that doesn't get boring as there is incentive to improve with the electronic recorder. The price isn't too bad either nowadays.
