M1 (Hard Mode | 100% Hit): Maximum hit and responsiveness. Perfect for crisp, single-pass linework and packing solid pigment on tougher skin areas.
M2 (Soft Mode | 85% Hit): A cushioned, forgiving hit. Ideal for smooth black-and-grey shading and working on sensitive skin areas.
M3 (E-Soft Mode | 10%–100% Dynamic Softness): Our signature smart mode. Fully adjustable softness that dynamically responds to skin resistance

Skip this if you mainly do
Heavy colour packing or large saturated fills
