Introduction

Powerball gyroscopic exercise tool is great device to build strength of hand’s muscles but is very sensitive to accidental dropping.

Too sensitive in my opinion which could be a part of producer's way of doing business. Hope I'm wrong.

OK, my Powerball felt from sofa and after this it was very hard to make it spin and when it eventually started I feel strong vibrations with accompaniment of annoying sounds.

I asked shop for repair but they told it’s beyond warranty.

So, if warranty is no longer the problem I just opened it and I have found a way to repair it.

Here is the guide.

Look at these surfaces and you will find several small deflections. They were made by gyro’s axis when it hit the floor. These deflections put up resistance during rolling and this is the reason it’s so hard to spin device.

Use some sharp tool and remove surpluses, make these places as smooth as you can. From time to time put gyro back in place and roll it on both halves of housing until you’ll feel it’s enough.

Put whole device back in reverse order and test it. The more you will spin it, the smoother it will work. The best thing is: you can fix it over and over again and you don’t have to pay again.
