It is normal for the gyroscope to make a sound when it rotates. It is recommended that you place it on a horizontal surface or rotate it vertically. Try to avoid tilting it when you place it on your hand. It is normal for it to shake slightly when your hand is unstable.Please do not wash it with water, because the rotating ball in the bearing will have resistance when it touches water, affecting the rotation speed.
This gyroscope is processed by CNC precision machine tools with more than ten processes. It is made of all-titanium alloy CT4 steel, and the surface is anodized, which will never fade.
