So, let’s get started,

An Overview of the Slinger tennis machine

The Slinger tennis ball machine is composed of 3 sections. The first feature is deep pockets that hold rackets and other tennis items. 

Secondly, there is the ball hopper, which contains the balls, and thirdly, there is the control panel, which allows you to adjust ball speed, feed rate, oscillations, etc. 

Moreover, there are extra pockets for you to put your personal items in, plus extra bags for water bottles, a towel to wipe sweat, and USB charging ports.

Initially, you’d think this machine would be heavy and difficult to maneuver, but it’s not like that at all. The Slinger bag has very fine wheels for easy maneuvering and two straps that allow you to lift the machine into the car. 

The wheels of the slinger are slimline, calm, and rounded with light rubber for smooth navigation. 

If we talk about slinger power, you just need to plug in the electric socket and it will automatically stop charging when it is full. However, you can also charge the battery by removing it from the machine and charging it individually. No worries there are not any technical skills to do this. It is quite simple. 

Overview of slinger machine

There are two knobs to control the speed and feed rate. Right below the knobs, there are four lights that show the battery level. These four lights are only present in the slinger bag which is helpful to know how long you can play on the court. 

Let’s move on to our review and our findings on the Slinger bag that will help you decide if it is the right machine for you or not at all.  

Nevertheless, the Slinger bag has no built-in oscillator, you will get it separately. When you want to face oscillations you have to put the machine onto the oscillator. After that, you need to give it power by connecting a white cable and that is all. The machine will start throwing oscillating balls.

Before moving into the complete depth of the Slinger Bag, let’s Understand the Slinger Tennis machine.

Slinger Bag vs other Machines

This tennis brand has surpassed other tennis machines. Other tennis machines don’t offer ball pickers, camera holders and racquet holders, etc. But this tennis brand has so much to offer.

First of all, you wouldn’t have to move across the court, set and pick a single ball and then go to another side to repeat the same to pick up balls. The slinger bag comes up with a ball picker tube. All you need to open the ball picker and get this done within a few minutes without getting agitated.

As we all know this is a digital time. We all go live on our social media and we make vlogs and take pictures to show our friends and family our daily routines. That is why the slinger bag machine came up with the idea of a camera holder to make it easy for you. That is what makes the Slinger tennis machine outperform all tennis machine makers.

Slinger Bag Tennis Ball Machine Review

slinger ball machine reviews

Slinger bag tennis machine brand has four types which have the same basic functions like ball speed, frequency, elevation, and navigation. However, all these four types have little difference in some extra features some have camera holers and some have 1 case of tennis balls and some with 2 cases.

Slinger Bag launcher has so much to offer. There are so many tennis machines on the market but I haven’t seen and played with a machine that comes with a full package like a bag where you put your tennis racquet and your balls and have remote controlling options as well.

You will have plenteous of pockets that allow you to place your phone your wallet and your cables without any difficulty.

Moreover, you would have noticed that Slinger ball Launcher has beautiful shape and color combinations. The bag is made up of high-quality waterproof stuff but I will suggest not playing on rainy days.

The Slinger bag allows you to charge your phone as well on the court as this ball machine has a very powerful battery that helps you stay up to 5 hours on the court and hit strong volleys.

Let’s check out some infographics of the machine.

How Slinger Tennis Ball Launcher is different than other traditional machines?

Slinger ball launcher is a totally different tennis machine as compared to others. The Slinger ball launcher comes with a bag for everything. In contrast, other tennis machines do not have bags. There are many other features on Slinger Launcher, such as a ball picker and a camera holder. 

If we only look at the ball throwing and navigation of all tennis machines. It’s still the Slinger ball launcher that stands out from the rest. 


The slinger machine has large, smooth wheels and a strong handle, making navigation easy. Additionally, you can customize the machine to your liking. To some extent, you can control the ball speed as low or fast as you like. 

The Slinger tennis machine is exactly what you would need if you were a tennis player since it provides all the functions and facilities needed to play and practice all the tennis shots you can imagine. 

Why Slinger Tennis Ball Launcher is the right machine for you?

The Slinger tennis launcher is the perfect machine for you. If you don’t like machines with multiple parts, which disturb you when maneuvering them or putting them in the trunk. 

There are many things that fascinate you about the Slinger machine, like its compact shape, the fact that you can close every part of the machine after playing, and that you can put a tennis racquet inside of it and zip it up. There is no other machine that offers such ease. The main purpose of the Slinger machine is to ease tennis players’ lives so they can focus on just practicing and playing. 

When you’re looking for a machine with a lot of functions and without too much hassle of adjusting and fixing it, this machine is a good fit for you. 

Ok! Let’s jump into some key specifications and pros and cons,

Key specifications.

Slinger tennis ball machine review/ slam pack

Slinger slam pack helps you to play comfortably on the court. The Slam Pack is a little more evolved than the Slinger bag launcher. This is a good machine for beginners.

However, the weight, ball speed, and frequency are the same but you will have an oscillator included in the same package, not like the launcher.

The oscillation work’s like the same machine which has built-in oscillations. But here you just have to put the current cable into the machine in case it starts oscillating.

Moreover, the best part of SLINGER SLAM PACK is, that it has some more functions like a camera holder, Ball tube, but the elevation and ball frequency is the same as the Slinger machine.

Most of the time I ask one of my friends to come with me on the court to record my amazing skills. But when I started playing with the slinger bag machine I just put my camera with the camera holder and record myself without asking for help.

Nevertheless, Slinger Slam Pack is the machine that will help you to enhance your skills to the next level without any disturbance.

If we talk about the voice of the Slinger Slam Pack while playing, there is a little voice that will not disturb you or anyone around playing.

How SLINGER SLAM PACK is different from other Machines?

Slam Pack machine is totally different from all other tennis machines on the market. I believe this machine is designed for players who have an end goal in mind. As an example, if you want to practice oscillation, you can bring the oscillator along with the machine. Otherwise, you can keep the oscillator at home. Because Slam Pack comes with external oscillations, you can remove the oscillator. 

The Slam Pack machine has a ball collector, which makes this machine a little more advanced and different from other tennis machines that make you bow down and collect the balls by yourself. 

Over the course of my 10 years of experience using tennis machines, I have yet to see a machine that allows the user to put everything into the machine bag and move it. Even you can put your phone in the bags and you can put your camera and you are able to keep your tennis racquets including balls and close the zip-up. 

Why SLINGER SLAM PACK is the right machine for you? 

If you travel a lot and need to manage a lot of stuff with you, Slinger Slam is the perfect tennis machine for you. If you are a videographer and you have to make videos. You will find the Slam Pack tennis machine to be the perfect choice in this situation.

Moreover, this is the digital era and we all keep our friends and family updated about our daily life. So this machine allows you to put your camera or phone in the camera holder and make videos, go for live calls, or take some pictures. 

Furthermore, it is highly customizable, easy to maneuver, and a compact machine. If you are looking for all these qualities in a machine, then this is the right tennis ball machine for you.

Key specifications of SLINGER SLAM PACK:

Weight: It has 33lbs/15kg and can say be very lightweight to navigate.
Dimensions: 14″ x 18″ x 34″ (35.6cm x 45.7cm x 86.4cm)
Elevations: 10 to 40 degree
Ball frequency: 2 and 7 seconds.
Controlling: Remote
Minimum speed: 10/16 mph
Maximum speed: 45/73 mph


  • It has a ball tube
  • You will have a camera holder
  • You can charge your mobile phone
  • Very lightweight
  • Easy navigation
  • Comfortable handles and wheels


You wouldn’t be able to know when the ball finishes in the hopper.

Bottom Line: The singer slam Pack ball machine is all set to hold most of your necessary gadgets. You can charge your phone and you can control the machine from another side of the court with a remote controller.



As we move further you will see Slinger slam is more leading than the prior two machines.

However, this device is not much different when we see the ball speed and ball capacity or oscillation but you will have a case of tennis balls.

If you are just starting out as a tennis player, you will not need high elevation but if you are a good tennis player, you have the option to change the elevations of balls from 10 to 40 degrees. that’s the catch for pro tennis players.

When your machine is full of balls and all other accessories you will have no issue with navigation, but if you are steering the machine in a rough area you will have difficulty like you will notice that the machine is slightly heavy.

During oscillation, you don’t have to control the slinger slam pack-1 by the control panel, you can use the remote controller to control the machine from another side of the court.

By the way, slinger slam pack-1 is one of the best tennis machines that allow you strong drills and good oscillation which will make you skill full tennis player.

Weight: It has 33lbs/15kg and can say be very lightweight to navigate.
Dimensions: 14″ x 18″ x 34″ (35.6cm x 45.7cm x 86.4cm)
Elevations: 10 to 40 degree
Ball frequency: 2 and 7 seconds.
Controlling: Remote
Ball capacity: 144
Minimum speed: 10/16 mph
Maximum speed: 45/73 mph


  • Easy navigations
  • Lightweight
  • Good feeding rate
  • 1 case of tennis balls
  • Ball tube
  • Camera holder


  • Max ball capacity is 144
  • You wouldn’t be able to know when the ball finishes in the hopper.

Bottom Line: There are so many gadgets and tools in the slinger machine that are not necessary to keep within the machine always. You need to know about your stroke and your routine. For example, if you are not in the mood to face oscillation, you can leave the oscillator at home.


Here we go, the last one from the Slinger bag brand. It has 2 cases of tennis balls. There is not much difference between but only 1 case and 2 cases of tennis balls.

You will find it the same machine which you have read on number three. However, there is one drawback, you will have 3.5 hours of playing time on average as compared to the Slinger Launcher.

Nevertheless, You can also get a machine for your dogs, which will keep your dog happy and busy as well.

Why do we like the slinger bag machine?

There are so many reasons and things that make us like the slinger bag machine. First of all, we liked the uptime of the slinger ball machine. If you get a new slinger bag machine you will notice that this machine is long-lasting and works smoothly for years without much maintenance. But you have a clean-up machine after every match and that is a fact and necessary.

Another thing that we like about the slinger ball machine is the one in all stuff. There is no such machine that is a complete package. Slinger is the only one that has a ball collector, camera holder, and multiple bags to keep your all gadgets in it even tennis rackets.

Third thing, The looks, and the structure. I think I am the only Slinger user who likes the structure and the bag color scheme and the design of the machine. In my opinion, there is no such machine better than a slinger.

Slinger bag Hacks and Tips

Slinger bag is a mysterious ball machine that brings much ease and creativity into your tennis game. So, there are so many hacks and tips that are not much known by everyone around. Here I have compiled a few hacks and tips for slinger ball machines.

As you know the machine is full of pockets and you can carry essential gadgets like a phone or camera etc. But I would recommend you should also keep a kit of screwdrivers and some towels in it. The screwdriver will help you to fix any technical thing during the match and the towel will be good to clean your sweating 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. But I would recommend charging your machine every day after finishing the match. Or you should charge the machine before going to court.

You have the option for a camera holder but you don’t 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 don’t know how to clean the slinger bag properly right? Slinger has so many pockets and you have to grab a vacuum cleaner that will suck all the dust out of it.

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

So many people do the mistake of buying soft and normal balls. That will net let have good tennis play. Always keep in mind to buy the high pressurized ball for the slinger bag. Here is a hack, when the machine through your ball and it sounds weak that means the balls are not suitable for the machine. On the other side, if the ball sounds solid that means the balls are super compatible.

Last tip but not least, you should bear a little more expensive of getting one more ball tube. When you will have two ball tubes you will easily pick the balls and save time as well.
