Those things are freaking awesome, a friend bought it.
I don't like the size though, or the instability.
I prefer my own plastic one, carmelized popcorn tube, and the biggest waterbottle I could fit in it. It works like a charm. And when you buy round bowl peices, the bowl peice will just sit on top of the waterbottle becuase of the spherical suction. No shitty metal/plastic top required.
