The Oster A6 slimmest 3 speed clipper combines the most compact ergonomic design ever built with a high efficiency, precision tuned, heavy duty motor that runs at over 4,000 SPM. It also features a patent pending drive system to provide an ultra smooth and efficient cutting experience. Weighing in at just 12.7 ozs, it’s our lightest clipper yet! Patent pending VIBRATION ISOLATORS are centered around the motor to help absorb vibration and noise, resulting in added comfort for all-day grooming.
