This cordless hair clipper and hair trimmer duo is high quality, high performance and high power. Both the hair clipper and hair trimmer feature a turbocharged, long-life microchipped magnetic motor which runs at 10,000 strokes per minute and has over 5,000 hours of motor life. Both clipper and trimmer include the highest quality Black Diamond Carbon DLC blade which stays cooler, rust-free and sharper longer. Both clipper and trimmer are powered by a lithium ion battery with 120 minutes of runtime and 105 minutes rapid charge (mains power supply). The trimmer has a removable drop top option for a skeleton-style design to expose the blade for cooler operation, better sight line and enhanced precision. Professional power goes Rogue!
