Emerald green with a vibration you feel instead of a light you see. That's how the AiroPro keeps things discreet. The aluminum alloy body has an ergonomic shape, and pods click into place with a magnetic fit, so changing strains is quick. Airo designs the hardware and oil together as a closed-loop system. It charges through USB-C. Wipe the contacts occasionally with a soft, dry cloth to keep every pull consistent.
