This is nothing more than a plant saucer. Nothing fancy and way smaller than I expected. I used to to keep my exercise ball sturdy when I use it as a chair at my computer where I do my Amazon reviews. I stopped using it because it made no difference and was actually in the way. To hold a ball in a garage, it'll work fine. But so will a paper plate, a piece of rope, or just about anything else you can come up with.
