The Remington HC8510 Genius is a complete hair clippers kit. The set includes barber scissors, a cleaning brush, and 10 comb attachments with a shaving length between 3 to 40mm. These attachments allow you to choose the right shaving length, and the click system ensures that the shaving length will stay the same throughout the grooming session. If you're going for a buzzcut, use the hair clippers without comb attachment. You can use the dial to choose from 5 lengths from 0.8 to 2mm. The hair clippers last up to 50 minutes on a full battery, and you can see on the display how long the battery will last. After use, you can store the hair clippers in the included storage case or place it in the charging dock.
