Terribly high 3

The ball is pretty much the worst I've played with.
I am certainly not a professional, but even for the hobby is this "grooved marble" useless.
The extremely smooth surface that you can really compare with a marble slips the ball in places completely uncontrollable across the table.
Pinching and the like is absolutely impossible.
Also, the ball rolls through these grooves in slow play strange curves.
And on quiet game I want to quickly say a few words because quiet is something else.
If the ball touches the gang there is a more than clearly audible loud bang, and the roles he is much louder than other balls that probably comes through this groove.
One can only warn against these false production and advise everyone to leave it alone.
