The CNC Kronos E402 wireless tattoo machine is a solid choice for any professional looking for a clean, no-frills tool that delivers reliable performance. Its fully adjustable stroke of up to 4.5mm offers great versatility, allowing you to switch from buttery smooth to hard and punchy with ease. The machine is well-balanced and comfortable to hold, thanks to its uniquely shaped grip. I really appreciate the convenience of the two full-color screen battery modules that provide excellent battery life and display useful information such as volts, Hz, battery level, and a timer. The controls are straightforward—no complicated jump start, memory presets, or dot mode—but it does include handy features like auto screen dim and auto shut-off to save power. The included padded travel and storage case is a nice bonus, making it easy to transport and protect the machine. While I wish CNC would offer an RCA adapter for more flexibility with power supplies, this wireless unit runs smoothly and consistently with a broad usable power band. Overall, the CNC Kronos E402 is a reliable, professional-grade tattoo machine ideal for artists who prefer simplicity without sacrificing quality or performance. Highly recommended!
