Bests & Worsts Reviews from Amazon

Love this set up! It's a little difficult to get used to at first, but as long as you start with the black ball, and start with small punches, (think tapping it with your fists) until you get the rhythm, you should progress quickly. After just under a week, I've progressed to the red ball. The headband adjusts well, it fits me without issue and I have a pretty large head. The material for the balls is soft and spongy so while it can come back and hit you, it's soft enough that it doesn't hurt. You can probably make something similar for a few dollars less with a tennis ball, some elastic string, and either a headband or a hat of some kind, but for the time and money you'd invest, and for the material of the balls in the set, with the ability to increase the difficulty level I would recommend spending the few extra dollars on this set up, especially for beginners.
