Review on Gamma Sports Tennis Ballhoppers: Durable, Convenient, and Stylish - Multiple Styles and Colors, Easy Pickup and Storage - Holds 50 to 140 Tennis Balls by Michael Jenkins

Poor construction and materials. The first time I used the funnel it broke. The weld on the cross member on one of the legs had cracked, rendering the funnel virtually unusable. I chose to have it repaired rather than return it as I live in Canada and ordered it from the US (didn't want to deal with the hassle). I ended up wrapping the connection in wire and used a two part epoxy to coat the hell it. I then had to reshape the leg so it still locks in an upright position. Now it looks ugly but usable. The bars at the bottom are also very weak (they make the balls fall into the basket). They warp, allowing the balls to fall back out, and I have to manually straighten them at least once every time I use the hopper. This is my first funnel so I don't have a comparison but overall I'm not impressed and wouldn't buy it again.
