My experience with the Tennis
Twist Ball Machine
My first exposure to the tennis twist was on a
A group of adults and I were using it for
some hitting practice.
I remembered that I wasn't very impressed
It wasn't powerful enough to feed the
balls over the net, it just tossed the balls a
few feet so you had to place the machine close
to you on the same side of the net. It tosses
the ball in a short arc just like how a parent
might feed balls to a kid, but it pushes out the
tennis balls a little faster.
The construction of the machine is as basic as you can
get allowing it to be the cheapest ball machine
on the market. It
only holds 28 tennis balls which sit on ramp
that twists around the machine. The steep angle
of the ramp provides the means along with
gravity to feed the throwing device.
A small spring controlled arm flips the
balls into the air using a small electrically
To keep the costs down it doesn't use a
battery, only an electric cable.
It's a very short in length one so you
need to use the machine with an electric
Running only on electric power really
limits what courts you can play with it at.
The machine only has one control - the
There is a device under the bottom of the
ball machine that allow you to adjust the spring
for the throwing arm, by changing the spring
tension you get some control over the throwing
angle and thereby the arc of the ball.
The speed is constant (about one every 5
seconds) and once you start-up the machine the
tennis balls are kicked out of the machine until
it runs out.
A year later I came across a Tennis Twist that someone
had thrown away.
I picked it up even though I already
owned a much better ball machine - the Prince
I figured that I could use it as a loaner
that I would supply the machine to people with
It was good for that purpose, but that's
I sometimes carried it to the courts when
my Prince ball machine's battery wasn't charged
up or when I just didn't feel like dealing with
dragging out the much heavier machine.
When I used it for practice the only
useful thing that I like using it for was to
practice my backhand volleys and backhand
overheads, everything else was too easy to do
with the easy ball feeds.
After moving away from courts that had no electrical
outlets the machine sat a few years in my garage
with no use so I dropped it off at Goodwill so
that they could find a new home for it.
My advice to adults players or serious juniors players
would be to get a real ball machine and if you
don't have the money for that then just pass on
the Tennis Twist.
Adults with small kids might find it
useful, but only if you have access to a court
with electrical power (not common on most public
courts unless they are lighted, even then they
often do not have an electrical outlet).
found out that they also offer a battery
operated version of the Tennis Twist. Since it
uses six ‘D’ size batteries you don't have to
worry about running out of power because you can
always keep an extra set of batteries in the
