  • Restore Pressurized Tennis Balls In 50 Seconds

    Pressurize In 50 Seconds. 🎾 Restore tennis and padel balls with 30 PSI control for fresh bounce every match.
    Tennis and padel balls do not die because the felt wears out; they lose pressure. Airmaster brings the bounce back by reversing pressure flow, restoring the internal PSI so each opening feels like a fresh can. Pressurize the whole can in about 50 seconds, then let smart control hold a precise target with closed-loop feedback. Switch between tennis at 30 psi and padel at 26 psi in the app, with real-time readings, ball life assessment, and savings tracking that can reach about $600 per year. A triple leak-proof build, auto-seal lid, and a safe vent-to-open routine make storage worry-free. At just 582 g with USB-C charging and an LED status indicator, it goes anywhere. Back Boundless-AirMaster: Tennis Butler. 68% Less Costs, 0 Waste. on Kickstarter now.
