Using this Adventek nail lamp is a breeze. First, charge the lamp fully using the provided charger. The lamp has a large 30,000 mAh battery, so it'll last you up to 12 hours. When you're ready to do your nails, place your hand or foot on the magnetic bottom plate. The built - in sensor will automatically turn on the light. For a pedicure, the magnetic plate makes it easy to position your feet. After you're done, the sensor will turn off the light, or you can use the ON/OFF 'beep' switch. There's a synthetic leather hand rest pillow on top for your comfort. When it comes to maintenance, keep the lamp clean. Wipe it with a soft, dry cloth. Don't expose it to water or extreme temperatures. And if you're not using it for a long time, store it in a cool, dry place. Enjoy your perfect manicures and pedicures with this amazing lamp!
