Past midnight, empty city court, no hitting partner… and I still got one of the best rally sessions I‘ve had in months. Because the thing across the net is the Acemate S10, and it actually moves. Two 4K cameras clock my shot the second it leaves the strings, it reads the bounce, then drives across the court on these Mecanum wheels — like 5 meters a second, reacts in about 0.15s — catches my ball and sends it right back. A full rally. I’m genuinely recovering my position and reading the next ball like I would against a real person. Wild. It serves too — up to 60mph, spin, lobs, whatever you dial in — plus 40-something built-in drills and an app that tracks your stats so you can see exactly where your game‘s leaking. And because it catches and reuses the ball, there’s none of that stopping every five minutes to pick up balls. You just… keep hitting. Hard, clay, grass — works on all of them. Folds down and fits in the car. Swap the battery in seconds and you‘re basically never stopping...
