I have 2 boys who play competitive tennis. I feed a lot of balls. I have the Gamma Travel cart, which is very good quality, but really heavy and very hard to unscrew the swing arms to fold the legs and put in and out of the car. This thing is a breeze! The basket unhooks from the cart, so it takes no more room than a wide bag of groceries and you don't have to worry about spilling balls as you are folding up the cart. The top handle slides out of the bottom and stores pretty close to flat. Unlike the gamma which is heavy even without balls, this is a breeze to put in the car by myself. Only complaint? If you have to drag this anywhere on grass, The wheels are all smaller than they should be. Go buy larger heavier wheels at harbor freight. And use a snap lock from the hardware store to keep the basket closed. You will be amazed at how many balls this basket holds. It's also a great height--about 4-6" taller than the Gamma Travel cart so you don't have to bend over to get balls out. I know this basket is great, because when my kids have lessons with their pro he prefers to use this one over his tourno basket or the gamma!!
