Really convenient
Have been using this reservoir for 25 days. I like to freeze some water in it before I carry. If the tube is frozen, it will not clip, otherwise it has been great. Unfortunately, this morning I found a leak near the bottom on the side. Returned it, am thinking that a fold with freezing water may have caused the leak. Since the original pack recommended freezing water with lemon juice to reduce plastic taste, it seemed the material could withstand freezing. Anyway, trying a second reservoir, I have really enjoyed the convenience of the fill and connect system.

Hanging method no longer a problem
I have had the same issue others had with the original hanger breaking off. The new design has been very reliable and does not break, as far as i can tell.
I really like the quick disconnect which means you don't have to reroute the tubing every time you refill. And I find that the fold over top seals well and makes it much easier to fill compared to the screw on top.

great bladder
I have a few sizes of these, this being the largest. Im not sure how people manage to break them, or have issues getting them open, they are dead simple. easy to clean, easy to fill. More importantly, if you have an issue, they will give you a new one. great company, great product
