I purchased the 36-pack, a bit skeptical about their claims. However, when they arrived I took them through a fairly intense smash/drive test for a couple weeks. Needless to say, they've been used and abused. They have been fantastic! Not an inconsistent ball in the 36-count package! They are a bit slower, probably because of a slightly more soft surface, and tough as nails. Strong spin doesn't make them wobble so they are very well balanced. The 9/10 overall is also due to the amazing value. I can use these as trainers and for serious matches.
