Damper characteristics: damping effect caused by the attraction of the magnet, because do not contact, no sliding friction, so the output torque is stable, persistent.
Change the Angle of one piece of magnet, can obtain different appeal, so easy.
Drive roller made from slingshot glue, enameled wire to scroll way, avoid scratch skin membrane.
Rotating components using light and fastening of material, the moment of inertia is small.
Compact structure, easy to install.
