Like another user review, I have also noticed that out of the box, the grit is inconsistent on the paddle. I have ordered 4 and on 3 of them, one side had clearly higher grit than the other. The other side felt smooth right around the sweet spot. I had to return those. I think this may be a manufacturing defect that Joola should address. I don't know if this problem also exists on the Hyperion CFS 16mm heavy, but it definitely is a problem on the 14mm heavy, being a new model released.The handleSee full review
