How "sticky" is it? Every time a non Chinese manufacturer claims "tacky" or "sticky" it's not. Can it hold a ball upside down for more than a second? Or pick up a ball from the table upside down?
I suspect it's the same technology as the new Donic Bluegrip J-series, which also claims a slightly tacky topsheet (the promotional picture show the ball sticking to the rubber), but these are also virtually non-tacky although extremely grippy.
