After the first four hours of playing, i finally get to write my review. (my first one, so please be gentle)
;-)
After takin' them out of the box, my first impression was: gee, they look a bit fragile. Almost as if i could see through 'em.
Totally different than my XSF Balls. (But those are not training balls, so hey...)
And the second surprise was: they're not seamless(!!), which gives me another good point to test.
The sound from bouncing on my racket is sounding completely different than any other ball i've heard before. But these are just first impressions, so next i'm heading to our practice hall...
I gave two balls to my teammates for testing and two for me and my practice partner. One of my teammates is more a hitter with mid pips on his backhand. The other one is a spinner. Both of 'em playing more than 30 years. So they know pretty much what they're doing.
My partner is also more of a hitter and driver and myself i would consider myself as a both winged spinner. So we were also able to test durability (after 4 hours of play maybe a bit early, but still...)
Well, my first impressions seemed to be wrong, 'cause the balls seemed to be selected. The roundness was close to perfect, as far as one can tell by eye-sight)
They also seemed pretty spin reactive. And when i say spin reactive i mean spin reactive. My black rubber left marks on one ball. I never had that before, but it was real hot in the hall today...
(The hall doesn't have aircondition)
I'll post some pics of those marks in the thread, so you can see what i mean.

Also the seam didn't seem to have ANY influence on the ball's bounce behaviour.
The bounce was pretty close to my XSF. Maybe not exactly that high, but still very constant. The arc they made while looping was pretty close to my C-Balls, and even closer to my XSF Balls.
Only irritating thing was the sound, but after 3 minutes, i didn't even think about that anymore..
The balls used by my teammates, didn't have any marks on 'em and the one guy's spin contains also a lot of rotation, but still no marks on the ball.
Well, both of 'em said they could hardly tell any difference to the XSF Balls we use every second training session.
But what one could see after they played, the ball was lookin' as if it had a little crack underneath the surface. It wasn't on it's outside, but more on it's inside. (I guess i have to post a pic of this in the thread as well.)
But that absolutely didn't seem to be having any influence on the ball's bounce. My teammates kept on playing with it for at least another hour.
So finding 4 hours is a bit short for a more objective review, i might update this review after some more hours of play.
Since i gonna rate them now, i'm gonna rate them 4 out of 5 stars.
They are almost comparable to competition balls, and seem to be pretty good for training balls.
I actually had competition p-balls that played much worse.
Thanks a lot for your attention.
