The Philips OneBlade Face + Body QP2824/10 is a revolutionary hybrid styler that can trim, shave, and create clean lines and edges on any length of hair. Forget about using multiple steps and tools—the OneBlade does it all while prioritizing your comfort. Its unique grooming technology features a fast-moving cutter that powers through hair at 12,000x per minute, combined with a dual protection system of a glide coating and rounded tips designed strictly to cut hair, not skin.(1 mm for a 5 o'clock shadow, 3 mm for a tight trim, and 5 mm for long stubble). Built for ultimate convenience, the OneBlade is fully waterproof (IPX7). You can shave wet or dry, with or without foam, and even in the shower. . The rechargeable Ni-MH battery delivers 45 minutes of constant shaving power after an 8-hour charge via USB-A
