15 minutes to set mine up. And even better, I haven't had to fool around with it since - something you cannot say about the typical BC, which requires that you "adjust" it every time you put the fool thing on!
I did it with just the plate and wing, then attached a cylinder and checked the adjustment. Made one small change in the crotch strap length and I was done. I made my adjustments with my CLOTHES on, not a wetsuit; it was just fine.
I cheated though - I put on two chafe protectors on the webbing on the shoulders (one on each side). If I dive a thick wetsuit (say, a 7 mil) I just remove those and the fit is back to where it is with my 3/2 - the neoprene gives me the chafe protection / comfort that I get with the pads
I can also don this thing on the boat without a big of trouble. By comparison, a standard BC requires that you fool around with this and that, making sure its snug at all the adjustments. Donning the BP yesterday was quicker than it has been for me with a "traditional" BC in the past....
I can see where people of particularly short stature might find them uncomfortable. I have no problem with it though, and really, really like the compact, "its part of you" feeling underwater.
