The Constant Control of the ER-GP80 ensures consistent cutting performance regardless of hair density. With conventional hair clippers, the speed of the cutting blade decreases as hair density increases, leading to reduced cutting performance. However, the ER-GP80 maintains the speed of the cutting blade consistently for precise results on every type of hair. The world’s unique, Panasonic-patented linear motor technology operates on the principle of magnetic levitation: the power transfer from the motor to the cutting blade occurs without friction. The brilliant advantage: completely independent of the battery charge level or hair density, the ER-GP80 cuts with constant power. This allows you to work faster and more securely. The carbon fiber and titanium-coated X-taper Blade cutting blade provides a razor-sharp, super-close cut – whether on dry or wet hair, fine contours, or complete machine haircuts.
