This is a wet or dry shaver, which allows it to be used in or out of the shower, with or without shaving foam. This also allows the shaver to be held under running water in order to rinse it clean after use. The three independant floating shave heads follow the contours of your face to give a close shave. To provide an even better shave, the center foil has slots to cut long hairs, while the two side foils have small holes to cut short stubble. The shaver runs on two included CR123A lithium batteries, which last twice as long as alkaline batteries giving approximately 60 shaves at 3 minutes each. Travel pouch is also included.
