My first impression was pretty good—it arrived well-packaged and set up easily, which was a relief since I'm always juggling dad duties. I've been using it for a couple of months now, and while it's fun and has helped me improve my game, there are moments where it just stops feeding balls or the shots aren't as consistent as I'd hoped. It's great for solo practice when the kids are napping, and I appreciate that it works with standard balls, but I wish it were a bit more reliable. Overall, it's a decent tool, but not something I'd rave about to friends without some caveats. 😊
- Pros: I really liked how this robot can throw all sorts of shots at me, making my practice sessions feel more dynamic and challenging. The adjustable speed is a big plus, allowing me to tailor it to my skill level, and it's super easy to carry around and store after use.
- Cons: From what I feel, the automatic feeding doesn't always work smoothly, and it can be a bit finicky with the balls, leading to some interruptions. The build quality feels a bit light, and I'm not sure how it will hold up over time with regular use.
