Regular punching bags are mainly for structure and power, not for precision and speed, although they can be, which can't be said for this ball on a stick
It’s a speed bag great for practicing precision, dodging and stuff, but punching bags are made for power. If your really trying to get into boxing you probably need some version of both, but a wall pad works pretty well for a punching bag especially if your working on accuracy since it’s a bit clearer where your hitting.
