So let me start by saying I should have looked at the size and read the reviews more carefully. They are smaller than the typical four square balls but I figured it was my fault despite the name. The reason they only get 2 stars is because they pierce easily. In less than 2 hours they were blown away walking in the yard or in the bushes. I live in the desert and I had several square balls and none of them punctured. Most of the time they have to be replaced because my kids leave them out in the hot sun. If you're buying these for four squares, I would recommend choosing balls with an x for four squares.
