When can I get one already!

You can reserve one now! Head over to our pre-order deposit page and select when you would like to receive your machine.

How much is it?

$1695 

How much are extra batteries? Do I need one?

Extra batteries will be available for $75 (we’ve upgraded the battery capacity to 5 A-hrs). You can get a good practice session (~1000 balls) on a single battery, but it’s certainly handy to have a spare around.

Will the metal lead screw damage a tennis court?

We’ve added a 1” diameter plastic foot to the lead screw, so it won’t be an issue.

Why are the “measured” speed numbers different than the competition advertises?

I can’t speak to how other manufacturers spec their machines, but in our testing machines with ~6” wheels (most portables have wheels about this size) max out about 70 mph. The ball has to accelerate from zero over just a couple of inches of contact with the wheels, and there simply isn’t enough friction to shoot faster than about 70 mph, even if your wheels spin faster. The Proton wheels spin as fast or faster than any other portable we tested, which allows us to hit the 70 mph max speed and still have wheel speed left over for spinning the ball.

How many balls should a ball machine hold?

We think 100 is plenty for portable use. The typical bucket of pressureless balls you can buy holds 48 balls. Carrying more than two of those to the court for your practice would be difficult. And with the way a custom Proton drill can make you run, your legs will agree that 100 is all you need.

How is your machine so light? Surely that comes with compromises?

You might think that, but you would be wrong! There have been significant advances in motors, batteries, and computer control, and no one has designed a machine from the ground up for portability and efficiency the way we have. Numerous features of this design are patent pending.

Does your app work with Android as well as iPhone?

Yes.

Do you have an Apple Watch app?

Yes, it provides start/stop functionality, and can upload any of the programs you create on your iPhone.

What warranty will it have? Will you pay warranty shipping?

The Proton will come with a 1 year warranty, and Hydrogen Sports will pay shipping both ways for any issues. We’re doing reliability testing on all the major components so it should last years and years, but if something comes up we’ll get you back and running as fast as we can!

Will you ship outside the US?

Eventually, yes, but for the initial launch we are doing US only. Again, just simplifying so we can focus on the essentials of releasing a great product.

Is shipping included in the price?

Unfortunately not., but ground shipping in the continental US is only $25.
