Purchased from Wizard. Used for approximately 10 hours. The Sol Nova Unlimited II, an improved version of the Sol Nova Unlimited, features a built-in display on the battery, making settings easier to see and control. The display rotates to match the machine's tilt, eliminating the need to set it for right- or left-handed use. You can also increase or decrease the voltage by pressing the button on top while tilting the machine's tip up or down. The built-in brushless DC motor has also been upgraded. You'll experience its stable power, while maintaining the quiet, low-vibration operation characteristic of Cheyenne machines. The machine has four different modes for setup, allowing you to customize the settings to your needs. ▽Four Modes▽ ・Steady Mode: Ideal for hard hits, such as for lines. ・Responsive Mode 3: Best for smooth shading with bright tones. ・Responsive Mode 2: Ideal for the remaining shading and color packing. ・Responsive Mode 1: Best for solid fill. Steady Mode delivers a hard hit to the needle at a constant strength. The motor responds by sensing the resistance against the skin and always hitting with the same power. Responsive Modes become harder from 3 to 2 to 1. It's recommended to start with Mode 3 and change modes as you progress through the procedure. By adjusting the modes effectively, you can minimize the burden on the skin.
