Advice about a Powerball

[Lil' Joe]

As my shoulder is still recovering (see Manly Scars thread) I bought a Powerball gyroscope thing to exercise a bit. However, the one I was thinking of was smaller and sounded as if it had ball bearings in it, not plastic and large like the one I seem to have got. Someone at Uni had one like that I'm sure they did, or am I imagining the smaller metal-sounding one?? If so does anyone know where to get the one I am thinking of?


Anyone else wanna buy a Powerball?
