Buffing away unwanted rough, dry skin on your feet has never been easier! The Pop Sonic Pedi Pro Electric Pedicure File buffs the bottoms, sides, and heels of your feet in the comfort of your home with two speed options. How do I use it: Press the power button once for low, press the button again to switch to high. Press again to turn off. You may also hold the power button for three seconds to turn off. Gently move the roller head back and forth on the rough areas of your foot. Do not press too hard and do not linger in one spot for more than a few seconds at a time. Note: if you use too much force the file will stop spinning. Keep moving around on the rough areas until you are left with smooth and delicate skin. After each use, rinse roller head with water to remove buildup. When the battery light is red, it means it is time to charge your Pedi Pro. From Pop Sonic.
