For all swing and rotational purposes this rope ball does what it should. But once I got competent at the motions and with the tool to start adding slams into my movements the ball only lasted a couple of work outs. Especially being that i got the biggest one, and most pictures show models using this to slam it into the ground, it should have been able to hold up to a little more powerful slams (and I'm a regualar hobby athlete, no out of this world explosiveness coming from me.) After getting to my second work out, excited to continue getting better at my slams, the ball split in half half way through my set. unfortunate, this was becoming one of my favorite tools.
Yes, I recommend this product
