Donic Avantgarde 3 star ball

Sir, are the Donic Avantgarde 3 star balls good? In a website the description says as follows: 

DONIC has developed a production line to incorporate the highest standards and quality control:
Specially selected celluloid raw material according to hardness and colour
Selection of the pre-cut ball halves according to thickness and weight
Tight manufacturing control of the ball seam
Control and selection of the ball diameter (along both axis)
Selection of the ball according to the weight
Triple Quality Control and selection by roundness (veer and over all sphericity)
Verification of bounce consistency .

Does his ball have a seam as it is said in the 4th line?

Does this description prove good to this ball? Thanks

Hi Earl,

I never give too much weight to the descriptions manufacturers provide.  It is best to try them.

I haven’t used one so I can’t give you my thoughts.  Hopefully others have tried them and can help.
