Great Ball Hopper!
I take a Friday clinic with three other women from a pro at his court. We ordered four of these as a Christmas gift for him. The fact that they are open on top with no cover makes them perfect, because we can easily dump the balls we pick up into his large wheeled teaching caddy. They were easy to assemble, look great, and are very sturdy, the price was great, too! He was happy with the gift.
