A Few Words From Joshua about this machine: Super smooth and consistent machine. Powerful through the whole stroke but designed to back off slightly in the middle and back end of the stroke to prevent overworking the skin. Super versatile, great for color saturation, blending, and even black and gray. Plenty of stroke to hang out for nice traditional whips or back it up and increase the voltage for smooth saturation. Has a penetrating stroke down to 4 volts which is great for stippling.
