the best TT robot: double snakes?

    I came across a robot that has two throw wheels and claims to be fully automatic.  Since the website is in Chinese, I'm not really sure if I got the features right.  Here is my impression which may be wrong.  It can serve different spins in a sequence (this is where I'm not really sure).  It can oscillate from side to side (like other robots).  (It can also oscillate up and down (wonder why the others did not think of this?)  Things inside the quote verified to be wrong info.  I am sorry.

     It can produce side top and under like either a right hander or a left hander.  I'm not sure if it can produce something like more sidespin than topspin though.  The ball recycling system looks like it is better than the other robots too.  Plus I have the impression that they use bearings (ball bearings?).

     Could the people here who know Chinese confirm these things and also add more information about this amazing robot?  The model I am looking at is the FQJ-2.  Thanks.

      The head does not oscillate up and down.  Sorry for the wrong info.  It turns out that the head tilt is changed by remote control.  The oscillation is by remote too.  Also, it is not programmable at all.  I think what it does is solve the problem of having to go to the robot and manually adjust the head to have a different spin serve or a serve a different arc.  It also claims to solve the problem of ball jamming.

I could not access www.doublesnakes.cn but I read about it in www.detail.china.alibaba.com/buyer/offerdetail/56921833.html

Look at the price its about $900 USD

Maybe the high price is dampening the interest in this robot.
