So, let’s get started,


Slinger Bag Review and Overview

The Slinger tennis ball machine is engineered with three distinct compartments. The first section offers spacious pockets for storing tennis rackets and other equipment without having extra bags.

The second compartment is the ball hopper, where you can store the balls. You can store your ball within the machine, unlike other machines that make you hold balls in an extra bag.

The third compartment is the control panel, which allows you to adjust the ball speed, feed rate, oscillations and other settings according to your needs.

The machine is designed with convenience and organization in mind. It features extra pockets for your items, dedicated compartments for water bottles, a towel, and even USB charging ports.

You might assume that a bag with so many features would be heavy and difficult to move around, but this machine is different. It has sleek wheels for easy maneuverability and two straps for lifting and loading into a car.

The wheels of the bag are slimline, quiet, and rounded with soft rubber for smooth navigation.
The machine also offers easy charging options. Plug it into an electrical outlet, and it will automatically stop charging once the battery is full. You can also charge the battery separately by removing it from the bag without the need for any technical skills- it’s very simple.

Slinger Bag Review and Overview

It is equipped with two knobs for controlling the speed and feed rate of the balls. Right below the knobs, four lights indicate the battery level, which is a helpful feature for determining how long you can play on the court.

As you consider whether the bag is the right machine for you, let’s take a closer look at its features and capabilities.
It’s worth noting that this machine does not come with a built-in oscillator. To use the oscillation feature, you’ll need to place the machine on an oscillator and connect the white cable to provide power. Once that’s done, the machine will start throwing oscillating balls.

Before delving deeper into the review, let’s first understand the Slinger bag machine.

Slinger Brand Hacks and Tips

This mysterious ball machine brings much ease and creativity into your tennis game. There are so many hacks, and only some are aware of them.
The machine is full of pockets, and you can carry essential gadgets like a phone, camera, etc. But you should also keep a kit of screwdrivers and some towels. The screwdriver will help you fix any technical thing during the match, and the towel will clean your sweat and dry your hand.

If you play tennis every day for one hour, you don’t need to charge the machine for 3 days because the machine allows you to play for 3.5 hours per charge. I recommend charging your machine every day after finishing the match. Or it would help if you charged the machine before going to court.

You have the option for a camera holder, but you must know that you can also hang the voice recorder’s big mic. That will make you record your voice and the shots hitting sound.
After playing every match, you should clean the machine, but you must learn how to clean the slinger bag properly, right? It has so many pockets; you must grab a vacuum cleaner that will suck all the dust out of it.

There are so many bags in the machine, and most players need to keep all the bags open while playing, which will ruin the shape of the machine. Always remember to let the bag set a side up or down nicely so you wouldn’t see any scar of folding.

Avoid this mistake by considering buying a high-pressurized ball for the machine. Here is a hack, when the machine through your ball sounds weak, which means the balls are not suitable for the machine. Conversely, if the ball sounds solid, the balls are super compatible.
Last tip but not least, you should bear more expense of getting one more ball tube. You will easily pick the balls and save time when you have two ball tubes.
