+1 for the Aromamizer. The Bellus is a great tank, but I like the ease and versatility of the 2-post velocity deck.
The aromamizer has that horrible rubber ring.
Huge turn off. Just a janky design that looks like an afterthought.
That's why I chose the Bellus.
The velocity deck is neat and all, but I never had a problem with standard decks so I don't see the hype.
