I haven't been juggling for long, and most of my juggling experience is contact juggling, but these balls are suitable for a beginner. The size is decent, the build quality isn't TOO terrible, the main problem is consistency. The fillings can vary pretty greatly, and so can the shapes. This shouldn't be too much of an issue for beginners doing simple cascades, showers, etc, but once you get into more complicated tricks it can be an issue. I ordered 2 sets and I ended up getting 3 that are perfectly even, still cheaper than a single high quality beanball.
