After buying the Staneg tennis ball machine, going to the court became a lot more enjoyable. I can train at any time without the hassle of finding a partner. The topspin shots allow me to practice under near-match conditions. The level 10 speed is impressively fast—perfect for return training. The external battery is a huge convenience; I don’t have to carry the whole machine to charge it. One charge easily gets me through 4–5 sessions, which is a huge plus for someone with a busy schedule. The build quality is excellent and very durable.
When I bought the Staneg machine, I was looking for both versatile programs and portability. On online forums, people often mentioned “portable yet powerful,” and that describes this machine perfectly. While other machines reportedly have battery life issues, Staneg has worked fine all week on a single charge. Setup is easy, and I don’t need to move the entire machine to charge it. Packaging was careful, shipping was fast. A truly professional yet user-friendly model.
As a professional tennis coach, reliable equipment is a must. The Staneg’s battery is external and easily removable; when it runs low, I just swap it out and keep going. I saw complaints online about other machines where “battery degraded quickly,” but I haven’t experienced anything like that here.
We bought the Staneg machine to train with my child between school lessons. At first we were curious, but thanks to its spin and flat shot settings, it turned out to be suitable for all levels. It’s super easy to carry from the car to the court—light and very portable. With the remote, I can adjust everything quickly, and my child stays in rhythm. The battery charges at home, so there’s no need to move the machine to plug it in. The packaging came in a sturdy wooden crate, no damage at all. As both a teacher and a mom, I find this machine incredibly practical and useful.
I'm a professional tennis coach and actively use the Staneg machine in my lessons. It’s perfect for students who want to train independently. Level 10 speed is very fast and helps advanced players work on their reflexes. The spin shots are well-balanced and program transitions are smooth.
We originally bought the machine for our son, but I eventually started using it too. Practicing together has been a lot of fun. The programs can be adjusted for different levels, so it’s great for both kids and adults. It arrived in a very elegant and protective wooden box. When I contacted the Staneg team with questions, they responded in minutes.
At our tennis club, two of us bought one each and now we can train on two separate courts at the same time. It’s incredibly flexible, especially since we’re at different skill levels—individual practice is much more effective. Shipping was quick—it arrived within a few days. The machine is solid and doesn’t even flinch when hit by a ball.
I’ve been looking for a way to train on my own for a long time. Thanks to the Staneg machine, I can now go to the court even early in the morning for a solo session. The battery life is fantastic; even with multiple weekly sessions, I rarely need to charge. And being able to remove the battery to charge it separately is incredibly convenient.
I’ve been looking for a solo training solution for a long time. Ever since I got the Staneg machine, my free days have become much more productive. With the high ball capacity, I can get 30–40 minutes of uninterrupted practice per session. By combining flat and topspin shots, I can work on both technique and fitness. The programs offer good variety, and every setting operates very smoothly.
I use the Staneg machine both for myself and my 12-year-old son. While he works on his basic techniques, I stay in shape. The variety of programs is great—there’s something for every skill level. The machine can shoot both topspin and flat balls at different speeds, which keeps training interesting. Portability is another big win—it fits easily in my trunk and I can carry it to the court on my own.
