One of the balls I ordered arrived with a small puncture in them. The customer service team contacted me a few days after the order arrived to make sure I was happy with the product. When I explained that one of the balls had a puncture, they responded that same day that they would be sending out a replacement ball. Great customer service!
We have only had the balls for a couple weeks, but they are just as expected and perfect for 9 Square in the Air.
