This is my second purchase of 100 Onix Pure 2 Pickleballs for our Pickleball Group. The first 100 were purchased 3 years ago and have survived year round daily play on three outdoor courts for that entire 3 years. We still had some left, but were running low so we made another order. Most of the first 100 balls disappeared into people's bags over time. I only witnessed a handful (4-5) that actually cracked and became unusable. Considering we play outdoors through the winter, sometimes with the temperatures in the teens, we are super impressed with the durability and consistency of play of the Onix Pure 2 balls.
