Fusion Power takes comfort technology to a new level. It has independently sprung blades that adjust to your face and helps the razor easily cut through hair. It has an oscillating motor that delivers soothing micro pulses which help reduce friction and increase razor glide. A flexible comfort guard follows the contours of your face and pulls your skin taut for a comfortably close shave. It features a precision trimmer technology on the back of the cartridge that shapes all types of beard styles, and an indicator lubra strip that gradually fades to white when you're no longer getting an optimal shave, so you always know when to change the blade.
