MUCH better quality than some of the other ones I've tried. It's a great way to get some exercise in your day without feeling like you're just exercising. It's fun and while the speaker could be louder, I have great acoustics in my "gym area" and it sounds fine. I also wouldn't mind if it was bigger in diameter, but that's true for all of these boxing machines because they all run smaller than you'd expect. This one is the average size and it has several ways you can install it. Comes with very comfortable gloves and connects to your phone so you can play your own music. There are different modes and speeds and it play a sound when you miss to let you know. Overall, this is a super fun device that is great for adults and for kids and it will definitely get you to burn some calories.
