I have several times for well over ten years. Do a search. I don't go into detail anymore because it's not worth the headache.You may have no interest in a rEvo, but if you are going to call them bad, back it up. The rEvo has faults, every rebreather has faults. At this point you are just bashing for the sake of bashing. As you call people fanboys, you are just the opposite.
And as for bashing the revo, here I'll give you my own personal metric on the revo that I bet anyone who's spent more than 10 years in cave country will attest to. Other than donsix and capt jim, 9 out of every 10 people who show up on a revo to cave country are vacation divers who can't dive in trim, silt up the caves, and are just a general nuisance. If I just wanted to bash the revo I would lead with that.
There are probably some pros to the revo. There is a lot I dislike and yes, I've dove one. Its not a horrid death machine. Its just not something I think is worth its price tag (or the previously historical overhaul costs).
