- Who is eligible
- Every tennis ball machine in our reviewed catalogue is included, from standard models to smart and AI-enabled ones. The list covers the models we track and opens on current ones: those our automated price checks found on sale new in the US. Where a check could not tell, a model released in the last 2½ years stays and an older one is hidden. The checks can be wrong (in a spot check about 9 in 10 on-sale verdicts held up, and about 3 in 4 not-found ones). Tick Include hidden models we track to see every model.
- How they are ordered
- By Ranking Net Score: points from reviews and discussions plus points from BettaScore votes, with ties going to the product with more sources. Filters and sorts renumber the results. A product without scored evidence yet is not listed; it joins once its reviews are scored.
- Where the evidence comes from
- 101 public review sources across the matching products; open a topic on any card for the quotes behind its points.
- Where the filters come from
- AI features lists a machine only when a specific AI capability is described for it, such as tracking the player or adapting its shots. App control, programmable drills or a “smart” name alone don't qualify. A machine left out isn't confirmed to lack AI; we just haven't found a specific description.
- When it changes
- Products and review scores change when we publish an update (latest: October 16, 2026). Topic votes count at once, 0.1 points each; the order follows on the next page load.
- Who pays for it
- Nobody. No brand pays for placement.
