Still wished it locked to the cart but it's ultimately miles ahead of the usual bart cart designs.

I love having this bag for my cart and it makes it much easier to carry.

I have used my tennis hopper twice now and I love how easy it is to carry around, it is so light and easy to set up, and it holds so many balls. I ordered a second bag to hold a different set of colored balls so I'm not having to change the balls out of the one basket. I also ordered a carry bag to hold the stand for my hopper. I am so far very pleased with my purchases!

Great idea. However, some stability issues and the pegs for holding the bag to the frame do not stand up and out of the eyelet loops enough. Too precarious of a design. Just need to fix those problems and you've got yourself a top level product.
