I bought this set with the new big balls and the quality is there.
The bounce is consistent, even on smashes, and there are fewer unwanted roll-ups during play. The big balls are a game changer, but that suits me: the points are more dynamic and I get the same feeling I had when I first played roundnet and enjoyed long rallies.
Overall, having played on a SpikeBall Pro so far, I wouldn't go back.
