I've continued to use them on hikes to treat & store water.  They are still doing well. 
Cool.  I've been thinking about getting some.  I've got a Nalgene 3L self standing water bag in several of my kits, but the Nalgenes with there 2 or 3 inch hard capped openings don't pack at all well for PSK use.  The Aqua Pouch appears to be vastly superior to a condom.
