Setup
- Charge the Device: Before first use, charge the device for 2.5 hours or until the green light indicator is on. Use only the provided charging cable and a charger rated 5V 1A.
- Select Roller Head: Choose the appropriate roller head for your needs. Use the extra coarse roller for heavy callus build-up and the regular coarse roller for maintaining smooth and soft feet.
- Attach Roller Head: Ensure the device is off. Align the chosen roller head with the device and gently press it into place until it clicks securely.
Operating Instructions
- Prepare Feet: Ensure your feet are clean and dry, or use after a shower for best results.
