My observations after two uses are:
PROS
1. Seems to keep my water colder for longer periods which is why I bought it.
2. Water does seem to taste better than the water from my other bladders.
3. Easier to clean because of the opening on the end.
4. Quick disconnect hose is nice. Makes it easier to handle and fill the bladder, although the hose is a little long.
CONS
1. Does not fit any of my existing packs. The bladders seem to be less wide and taller than the camelbak or osprey bladders. This results in the system sticking out the top of my pack. This is not a huge deal, I just want it to fit and be secure although it worked fine on both packs.
