I have been using this hopper for a month and I from the moment I finished building I have been loving this hopper! It is designed to help you pick up balls and it is plastic so it's a lot lighter than the metal hoppers out there. Do have the Gamma and Wilson metal hoppers and actually prefer this hopper over the other two. Assembly is very easy, make sure you read the instructions and install the wheels on first before you put the box together. They do put that as the first step for a reason :P It's very sturdy for plastic, and a lot easier to switch to standing mode to carry/pick up mode than the Wilson. My Wilson actually fell apart because the metal is really thin and flimsy and the welding is really bad, so there were parts that fell off and I had to MacGyver it back together. I finally gave up and got this hopper, and to be honest I was very skeptical because the plastic element, but it has been a wonderful addition to my tennis accessories. A side note, I thought I would never utilize the wheels, but I find myself being relieved that I can roll my hopper over to pick up balls. Especially, after going through a couple full hoppers of drills and serve practice. Metal hoppers aren't that heavy, but overtime, have that lightweight carrier with wheels can make the difference between, okay let's call it a day, or let's go through one more.
