If you search I'm sure there's many topics on it, the main problem I believe is trying to vent and breathe of it at the same time is problematic (to vent you normally want inflator hose above head, to breathe off it you want it in your mouth). I almost bought one because it seems like a great idea, but Scubaboards convinced me it was a bad "advancement".Kind of WAY off topic, but what's wrong with Air2? Not trying to start a debate, just a quick answer would be good for my own general knowledge. LDS I am with has all BCs with Air2 in them.
Like anything else, some advancements in Scuba will be like the invention of the internet, others will be like New Coke.
