Solasilk comes with two speed settings so you can tailor each session. Press the switch once and the device starts on low speed, shown as "ONE" on the digital screen. Press it a second time to move up to fast speed, shown as "TWO." That way, you can dial the intensity up or down depending on how thick the calluses are and what feels most comfortable.

Swapping the grinding head takes seconds, whether it's for personal use or sharing the device. To take it off, grip both sides with your fingers and pull straight up. To fit a new head, press it down into the device until you hear it click into place. As a safety note, never turn the device on unless the grinding head is securely attached.

Start by removing the grinding head and dust cover, then use the included brush to clear away any skin dust — the device should always be switched off while you clean it. Thanks to its IPX6 waterproof rating, it can also be rinsed briefly under water. Just avoid salt water, water hotter than 60°C, and harsh chemicals like thinner, gasoline, or alcohol.

A full charge gives you roughly 60 minutes of use, though actual runtime can vary depending on how you use and maintain the device. For the best battery performance, charge, use, and store Solasilk somewhere between 5°C and 35°C.
