Is this REI mattress really THAT good?

Today I looked at and fondled an REI Flash air mattress. I laid on it back, front and side and it felt pretty good.

AND this sucker has a 3.7 R rating (this can be a bit subjective, I know). But even if t’sonly 3 4 that’s pretty good for a 15 oz. size Regular.  

Cleverly it has a one-way fill valve and a separate, fairly large empty valve.

So when did this very interesting mattress arrive? Has anyone here bought it? Used it? Abused it?

Anyone want to buy a 3 yr. old Prolite Regular? ;o)
