NSD Bluetooth Spinner Review 2023

Updated: Jun 28

Is it the world's best gyroball ever? We tested it.


The NSD BT Spinner (PB-700BT) connects to your smartphone via Bluetooth and the NSD App reads the rotations of the core.


The device is robust, well-made, apparently durable, and silent. The grip is comfortable and it feels good in the hand.


The pairing process took a bit longer than expected, but it was successful in the end. The App opens on the 'Real Time Monitoring' page. Other screens that display real-time RPM include the 'Individual Challenge' and the 'Versus Mode,' where users can compete against each other in person.





I tested the 'Individual Challenge'. The user has 30 seconds to do their best and observe in real time the total number of rotations, the maximum speed reached, the torque, and the average RPM.




I was able to place second in the world (for this week) with over a 10,000 RPM peak. To Shawn, who is ahead of me, I wish luck in this challenge, as this will be my last participation. Here´s why:

  1. The 'peak' in a gyroball, even the lightest ones, means the maximum possible pressure on the shoulder ligaments. Even controlled academic studies suggest this action by participants.

  2. Although it is an 'objective' way to measure the return of the equipment, trying to reach the peak will bring 2 results.

  3. One is that the non-dominant arm will work with a lighter load, as it will naturally be less activated. Over time, the muscle groups in the strong arm will become stronger and stronger. The aesthetic result can be strange...

  4. The other result is an increased injury risk.


So, despite the fun of ranking, I believe that the best use for the App will be precisely the rational monitoring of the exercise. The balance work between the arms will be facilitated by the graphic elements.







The metrics displayed have not been evaluated, but for the purpose of recording and evolution, the displayed data is very useful, regardless of accuracy.


The Gyrobull Academy's exercise series can be monitored using the timer of the 'Individual Challenge'.


With the restriction on the incentive for risky exposure, the device is very good.


In conclusion, I believe that this NSD Powerball with Bluetooth is a great device that offers a lot of potential for monitoring and improving one's gyroball exercises. The robust construction, comfortable grip, and useful App make it a great choice for anyone looking to take their gyroball workouts to the next level.
