Slinger - The Most Portable Tennis Ball Launcher

$731,170

 We had this crazy idea that quickly became a core mission for us: that everyone should be able to own a tennis ball launcher. We loved the concept of a tennis ball launcher, and always used them when we were at the clubs when they were available. 

 Warming up before a game, both mentally and physically, always has us at the top of our game. Problem is, they weren’t always available. Or easy to use. Or even good for that matter. 

 We knew that to make a tennis ball launcher for everyone, besides being simple and awesome, it would have to be both portable and affordable. So we got to work. And we couldn’t be prouder of the end product.

 Slinger allows you to easily control the launch serve using two customizable dials - speed and frequency. You can also manually adjust the barrels' angle to create a huge variety of serves.

 You asked so we delivered! Out 2 most requested features, both will be available for adding to your order right after the campaign.

Remote Control for Slinger

Many of you have reached out asking if Slinger is going to come with a remote. So while we weren’t planning on it, we’re making it happen. We have 2 stylish design ideas, which we’ll be asking you to vote on in the near future - either a bracelet or a key ring remote.

 Rotating Platform for Slinger

Spinning action! Nice. This is something we originally left out to keep our focus on the compact size and portability aspects of Slinger, but we’ve found a way to incorporate it without adding bulk… Meet the Rotating Platform!

It’s pretty simple, there are two plates - one sits under Slinger, while the bottom plate has a motor that rotates the top plate with Slinger in tow. This enables a wider range of shot-types and keeps you moving, shooting balls all over the court. These will also come with a cable that connects to Slinger for power.

Before manufacturing the rotating platform, we want to make sure the demand is there and need 1,000 backers for it. So if it’s something you want, send us a quick message and let us know.  

As with everything else in life, they cost money to manufacture. After crunching the numbers, the remote is going to add an addition $14.99 onto the price of Slinger while the Rotating Platform will be available for $95.
Both the Rotating Platform and the Slinger Remote will be made available via BackerKit, a survey we’ll send out as soon as our campaign is over. Keep an eye on your inbox for more details.

  “The best thing for learning, grooving and cementing stroke mechanics”

Check out this two short videos. Slinger in action firing balls with heavy topspin.

 Everybody knows that warming up before playing makes a difference, but few really know just how important it is. And not just for performance.  

Slinger warms up your muscles to avoid injuries and better flexibility. Plus, muscle memory means more effortless coordination. It makes your brain more focused on tennis. Because sometimes you need to remind your brain how to do things. Getting a feel for the racket, the court, the ball and everything else.

Risks and challenges

We have been working on Slinger's mechanism and final design for day and night for many months to ensure that everything works really well and it works as well as we envisioned. We're very confident we'll be able to execute production and delivery smoothly and on time.
Our prototypes don't just look great, but they work great too.
The next important milestone will be mass-production and we've already made a lot of progress on that front.
We know that unexpected delays could happen, but we're fully committed to ensuring all our backers will get the best product and on time.
