About this item

• TRAVEL LOCK: Enjoy the travel lock feature to help reduce accidental powering of the device. Press and hold the lock button for 5 seconds to engage disengage. Illuminate your grooming area with the built-in LED light, ensuring you never miss a spot. The bright, focused light makes it easy to navigate those hard-to-reach areas and achieve a consistently clean trim every time. Our trimmer also comes with an EVA Travel case for the man on-the-go.
• SKINSAFE TECHNOLOGY: Our updated Skin Safe ceramic blade is rounded for comfort with a built-in guard designed to help reduce nicks and cuts. Included are two adjustable comb attachments that allow you to trim from 2-12 mm. Skin Safe technology does not guarantee cut protection.
• EFFORTLESSLY POWERFUL: After fully charging your ball trimmer via USB-C or wireless charger, gently place the flat side of the blade flush against your skin and shave against the direction of growth. Constant RPMs help prevent the blade from slowing down as the battery dies, creating a consistent shave with up to 60 minutes of runtime.
• TRIM WET OR DRY: The waterproof* design allows you to shave in the shower or in dry conditions and you can run it under the faucet for easy cleanup. *IPX7 rated to protect against immersion in up to one meter of fresh water for up to 30 minutes.
• GROIN, BODY & BACK: Our trimmers were designed for below-the-waist grooming but work great on your not so private parts too! With our updated Skin Safe replaceable blade, you can have multiple blades ready for all body areas with hair. Feel more confident & comfortable with a total grooming experience.
