Question: I was hoping that this might work for baseballs as well. Is it strong enough for baseballs?
Document: Given the price, &#34;mediocre&#34; is to be expected. Usable, but a bit flimsy, The lid and the handles/legs need to be reshaped to work reasonably well, and the small &#34;bulb meant to hold the two handles/legs in the up (handle) doesn't do the job.
It was very easy to put together and works very well. I don't know how some people can complain about it. The price is right and holds a lot of balls.
Light weight. I have a design issue with the locking mechanism to keep the Hopper in the upright position. It is way too difficult to lock or release the handles to get the hopper to stand. I am going to try to spray WD-40 to lubricate the mechanism. It works well picking up balls and was priced great.
My girlfriend and I play tennis every Tuesday and she played in High School so we are big tennis players. This was a great gift to keep all of the balls together while we are playing since we don't really have pockets to hold the balls. It picks up all the tennis balls easily and stands perfectly while the ball is being served.My only complaint is that it is awkward to carry when walking back and force to the tennis courts so I wish it had wheels. Otherwise this hopper does well for its purpose.
This is a good hopper for my purposes. I am a regular tennis player. I use it for taking to the court to practice serves. I also give instruction to my grandchildren. I have had a hopper for years that has served me well, and while it was heavy duty it had no legs so I had to lean over to pick up balls. I decided to get one that had legs. This works very easily. It is lighter than my old hopper and it also picks up balls  with less effort due to the lighter weight of the metal frame.
My older ball hopper was falling apart from years of abuse (kicking, throwing, and other tantrums...). I purchased this because it was relatively cheap and I had some credit on a gift card. I works like any other but the one issue I have is the arms that lock when in the upright position is very hard to get set, I am hoping over time they will click in easier but for now it is kind of a pain...
Many people like me have a lot of balls that they bring around onto the court to play with. What I find annoying is the fact that you have to bend over and pick them up one by one and put them in a little bag of some sort to reuse them. This hopper solves all the problems. It's very light, but that's mainly because of a slightly cheaper material. It's easy to pick up balls with this, but the handle is covered with a cheap plastic which might break anytime. You can also lift it up so that it's in a standing position.
It is easy to put together works very well
This is useful, but the handles aren't very sturdy when doing so. Assembly was very quick and easy, although a little better instructions and packaging would have been appreciated. Overall a nice product that is well worth the money.
Does the job right.. Even my 6 YO can use it, she loves to use this. Handle converts into stand, make sure you check it is balanced well while converting to stand. Highly recommend.
