Pace S Pro

The feed is the product, and the feed is very good

Before anything else, a ball machine has one job: put the ball where the drill said it would, at the pace it promised, every time, without jamming. The Pace S Pro does that well, and independent testing backs it up — placement was reported as accurate and consistent, with jams a rarity.

80 mph matters more than it sounds. Plenty of machines quote a top speed you would never use, because at full pace they lose placement accuracy. Here it is a usable setting — fast enough to rehearse a first-serve return or a heavy flat drive under real time pressure.

The spin figure is the more interesting number. 60 revolutions per second is a serious amount of rotation, enough to produce a ball that genuinely kicks off the court rather than merely arriving with topspin on it. Paired with the claimed 1.5-second spin switch, a drill can alternate between a heavy topspin ball and a skidding slice within a single pattern — which is what makes practice feel like a rally rather than a metronome.

The 8.1 m lob ceiling covers overhead and smash practice, and the machine is rated across the full NTRP 1.0 to 7.0 range, so it scales from a beginner's slow feed to something a strong club player has to work at.

Six programmable placement positions. PongBot's own diagram is the clearest statement of what the machine actually targets — deuce and ad baselines, centre, service-box T, and left and right tosses, each with its own programmed drills. Note the wording: this is a fixed set of positions, not arbitrary court coordinates. Image: PongBot.

PongBot does not publish a per-shot interval range on the product page, which is the one figure we would add to this section if we had it. Ask before ordering if you have a specific drill tempo in mind.

564 drills is the feature people underestimate

Drill count reads like a marketing number until you have owned a ball machine. The failure mode of solo practice is not the machine — it is you, defaulting to the same comfortable crosscourt feed for the twentieth session running, because designing good practice is hard and you came to hit, not to plan.

PongBot ships 564+ preset drills, spanning simple single-position repetition through to full-court multi-shot combinations, and graded to skill level so the machine can suggest something appropriate rather than dumping the whole catalogue on you.

On top of that you can build your own patterns of up to 46 balls and publish them to a shared in-app library. That community layer is genuinely valuable and rare: it means the drill catalogue grows after you buy the machine, without PongBot writing a line of code. If you coach, it also means you can author a session once and send it to every player you work with.

PongBot also cites a Match Challenge mode built on more than 10,000 real match data points, intended to make the machine construct points the way an opponent would. That is the most ambitious thing here, and — see below — the least reliable.

Where the 564 number comes from. The library is built by combining shot types — forehand and backhand baseline, volleys, overhead smash, defensive retrieval, random rally — against the six placement positions. Useful context: 564 is a product of combinations, not 564 hand-authored sessions. Image: PongBot.

The AI: real technology, genuinely unfinished

This is the feature the marketing leads with, so it deserves a straight assessment.

The system works through three clip-on trackers supplied with the machine. PongBot quotes a 100 Hz sampling rate and 10 cm accuracy on player position. The machine uses that live position to drive several modes: adaptive rally settings that respond to where you actually are, an intelligent recovery trigger that waits until you have recovered before firing again, and the Match Challenge mode.

The concept is excellent. A recovery-triggered feed is a fundamentally better way to train movement than a fixed interval, because it rewards you for recovering properly instead of punishing you for being slow.

The three modes the tracking drives — adaptive rally, recovery trigger, and match challenge. Every one of them depends on knowing where you are, which is why the accuracy problem below matters more than it would for a cosmetic feature. Note the tracker clipped at the player's waist. Image: PongBot.

There is also a small hardware oversight that tells you how new this feature is: there is no storage compartment for the trackers. Three small clip-on devices ship with a machine that has nowhere to put them, which is exactly the sort of detail that gets fixed in a second revision.

The mitigating factor is real: the machine takes over-the-air updates. Tracking and sequencing are software problems, and software problems on a connected product genuinely do get better. But you should buy the machine you are getting today, not the one the roadmap describes.

Battery, hopper, and the rhythm of a session

Two numbers set the shape of a practice session: up to 8 hours of battery and a 150-ball hopper.

The battery is effectively a non-issue. No solo player is hitting for eight hours, and a coach running back-to-back lessons will still get through a full day. The one scenario where it matters is a club or academy running the machine continuously across multiple courts — which is precisely who the spare-battery bundle exists for.

The hopper is the real constraint. 150 balls is generous, but at a brisk drill tempo you will empty it, and then you are picking up. That is not a criticism of this machine specifically — it is the fundamental economics of solo tennis — but it is worth being honest that the eight-hour battery describes the machine's endurance, not yours. Plan for ball collection as part of the session, and note that a recycling net is referenced in PongBot's bundle options.

One consequence worth planning for: balls are not supplied with the base machine. A 150-ball hopper wants roughly 150 balls. Either you already own a basket or you add the 100-ball bundle.

Moving 45 pounds around

The Pace S Pro measures roughly 19 × 17 × 13 inches and weighs 45+ lb — about 19 kg net. PongBot has clearly thought about transport: there is a telescopic pull handle, luggage-style wheels, and metal grab handles for lifting.

On flat ground — car park to court gate to baseline — that combination works well and the machine tows like a suitcase. The awkwardness appears when you have to lift: into a car boot, up a flight of steps, over a kerb. Independent testing described carrying it as still somewhat awkward despite the handles, and 19 kg of dense, boxy machine is simply hard to hold close to your body.

Practically, this is a machine for players who can drive to the court and roll it in. If your court involves stairs, or you rely on public transport, weigh that honestly before buying — it will decide how often you actually use it, which matters more than any spec on this page.

App, remote, and updates

You get two control routes: a smartphone app connecting over Bluetooth, and a physical remote. Both ship with the machine.

The consensus — and it matches how these products usually work — is that the app is the better interface by some margin. It is where the drill library lives, where custom patterns are built, and where the community sharing happens. The remote's job is quick adjustments mid-drill without walking to your phone, and it is fine at that.

Both controls stay in sync. PongBot's claim is that custom drills built in the app push to the remote with one click — the arrangement that makes the remote genuinely useful rather than a stripped-down duplicate. Image: PongBot.

The genuinely valuable part is over-the-air updates. For a machine whose most ambitious feature is a work in progress, an update path is not a nice-to-have — it is the reason the AI criticism above is a "not yet" rather than a "no".

Set-up expectations honestly: there is a learning curve. There are a lot of settings, and the first couple of sessions will involve more menu-reading than hitting. That is the cost of the depth, and it fades quickly.

Who this is really for

The Pace S Pro makes most sense for the committed solo player — someone hitting two or three times a week who cannot reliably find a partner at their level, and who will actually use a structured drill library rather than just feeding themselves forehands.

It also makes strong sense for coaches. The eight-hour battery, the deep preset catalogue and the ability to author and distribute custom drills turn it into a second pair of hands during group sessions.

It makes less sense if you are buying it because of the AI. That feature is the newest and shakiest part of the product, and if the adaptive tracking is your reason to spend $1,239.99, you are paying full price for the least finished component. Wait a firmware cycle or two, or buy for the feed and let the AI mature around you.
