A year ago these seemed to be very popular, with tons of options being released. Now, not so much. Were they just a gimmick people grew tired of, or are they still seeing a lot of use? If so, which one do you prefer (post pics!)? Do they have as much flavor as 24mm tanks, or are they mostly for clouds, bro? From what I've found, the Aromamizer plus seems like the best option. Any others I should consider?
