Xushaofa Premium 40+ Training Balls ((Box of 120))

comparing to the artengo 40+ those balls appear to(a) have rougher surface causing the spin to have higher impact when moving on the table.(b) bounce slightly less when you let both fall at the same time(c) slightly more wobbly than artengo 40+(d) leave marks on the table when newOverall feel and play; they are less easy to control and slower due to the rougher surface and in comparison to the artengo 40+ which appear faster and easier to control.Also appear to be working well with my Tibhar robot.

These balls are seamless and work just as good as the more expensive seamed balls.

These are indistinguishable from the standard 3* balls that i had bought earlier. Perfect for robot practise too.

Seem to last well
