Using the Doxy Die Cast 3 Rechargeable Blue Flame is easy. First, make sure it's fully charged. Then, turn it on and select your desired speed from 3000 to 9000 RPM or use the escalating pulse setting for a more intense massage. You can apply it to different parts of your body to relieve muscle pain and tension. When you're done, turn it off. To clean the massager, simply remove the silicone head and wash it with mild soap and water. Let it dry completely before reattaching. Keep the massager in the included metal storage tube when not in use to protect it. Don't expose it to extreme temperatures or moisture. Also, avoid using it on broken or irritated skin. If you have any medical conditions, it's best to consult your doctor before using the massager.
