The Proxelli ARES Professional Trimmer features a 360° exposed ultra sharp T-blade to allow barbers to create and cut with precision, with a revolutionary blade that remains cool to the touch. The smart-clip technology senses blade resistance and revs up the motor speed, so the trimmer will never drag or stall. The lithium battery is fully charged in 2 hours and delivers a 2 hour run time, with an indicator light to show battery status. The superior motor boasts 7000RPM while being ultra quiet, with a noise level below 62dB. Can be used corded or cordless.
