The 540 model is virtually identical to the
1040/2040, apart from the ball container, recycling net and no oscillation
control. The robots and controls are virtually the same, so the
review of the Newgy 2040 very much applies to the
540 as well.
The controller allows you to adjust the
frequency and the speed of the ball... the more speed the more spin.
The head can be tilted, allowing you to get
different angles at which the ball are projected. By rotating the head, you can
achieve the different spins (ie topspin, sidespin (both) and backspin).
The fact that you can place the unit
anywhere, either on any position on the table, or even a position next to the
table, actually offers you a lot of flexibility that fixed units don't have. For
example you can place the unit close to the net to give faster balls, or well
behind the table for long range balls. People commonly put the unit onto to a
chair with height adjustment behind the table, offering even more options and
balls. It's really up to you and your imagination on how you can use this unit.
It is a simple robot, but very easy to setup
and use and has proven to be quite reliable. It does have some limitations, but
that's to be expected with the cheap pricetag, but also it's flexibility as
mentioned above, that many people may not have considered. The unit is highly portable...
you simple put it anywhere, plug it in, and away you go!
It makes a very handy and cheap training
tool for practicing certain strokes or drills.
A seperate catching net can be purchased
from some retailers, which help collect the balls. Otherwise one of those pipes
that pick up the balls would come in very handy.
