Have two of these, a 2L and a 3L, and haven't experienced either of the leaking issues (quick connect or lid) using in a Dakine Drafter or old MULE for MTB, an Osprey Karve for snow stuff, and an Osprey Ether for backpacking. I'm a notorious overpacker as well so there should be plenty of opportunity for gear to put pressure on the connections and the lid.
Definitely many improvements over the older 3L bladder that came w/ my MULE. The shape definitely seems to be much flatter, the lid is much easier to open and is wider allowing easier access for cleaning, the integrated stand and internal baffles make it alot easier to get it to stay open for drying, and the quick connect is a must have IMO especially for winter packs w/ internal insulated tube routing.
Barring any future problems w/ the leaking described by others, I'm pretty happy w/ mine.
