The tennis ball carrier broke in two places the first time I used it. My other pete sampras ballport lasted 20 years and never broke This one lasted about 20 minutes. The handles also are hard to snap in, leaving you with a lop sided ball carrier. The reason it broke so quickly is that the carrier is made of cheap, flimsy plastic. I would definitely not recommend anyone purchasing this product.
Had hours of fun with my ballport on vacation running drills with my wife and three kids. I love the compact size, it holds just enough balls for a quick pickup too.
When picking up 35 balls the basket would get jammed up making it hard to pickup all 35 balls. I like the weight and quality of the Ballport, but should have purchased the larger model. For me this small model would be ok for around 20 balls.
