It didn't work as I expected. CO2 bubbles simply bypassed the bullets and rose. One of the spheres rotated slowly while the rest did not move. Unless you have a "huge" tank and you're pumping out a massive amount of CO2 (more than 10bps), I don't see how this is supposed to work. As other reviewers have noted, the hardware leaks and I even had to superglue the bottom to keep it in place.
