It blew me away. I underestimated it. Very impressive! It's making me miss. Making me less of a man. Speed, reaction, fun, functionality. Incredible. I think it's useful for both fitness and boxing. Most boxers train a lot on their own. This is a great piece of equipment that's gonna keep it fun every single time. It's going to keep it fun every single time. And of course fitness! You see — I'm sweating. Can't go wrong. I love it, first time I've ever seen anything like it.
