Unlike other hair trimmers, the Flex trimmer is compact and lightweight in its ergonomic design and function for ultimate comfort. It is perfect for any travel kit along with everyday use. Small but powerful, it is equipped with a super-torque rotary motor that runs at 7,500 rpms and can be recharged with the micro-usb cord included in the box for worldwide use. The lithium-ion battery offers 3 hours of continued run-time and is fully recharged in 90-minutes. Assembled with the Gold Titanium X-Pro Classic fixed blade, along with The One Black Diamond Carbon Dlc deep tooth moving blade for the crunchiest, smoothest cutting with no pulling or snagging. Fully adjustable zero gap for the closest cut and finish. The open skeleton 360° design exposes the blade for cooler operation and better sight lines. Three trimmer guards (1/2", 1", 1-1/2") are included for maximum performance for all hair lengths. Last but not least, you get to fully customize this trimmer with nine different body modifications by changing out the two-part upper and lower lid for multi-color looks to suit your personal style. Engineered and designed in the Usa.
