The top-rated hair clipper of 2015 is the Oster Classic 76, according to BestReviews.com and Buzzcut Guide. BestReviews.com also lists the Babyliss FX811 Pro X2 Ferrari Cordless Clipper as one of the best hair clippers.
Oster's Classic 76 Universal Motor Clipper is durable, powerful and capable of cutting through thick hair. The device doesn't heat up significantly even after long hours of use, and most of its parts are replaceable and serviceable. However, this model is noticeably louder, heavier and bulkier than most home-grade hair clippers.
In contrast, the Babyliss FX811 Pro X2 Ferrari is lightweight and easy to maneuver, making it suitable for delicate cuts. Disadvantages include its expensive price and three-hour battery life.
