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.
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
