Purchased a full swig rig with bottle and another wide mouth lid with tube for an existing Nalgene I have. A one way valve was installed backwards, but you can pull it out and reinsert correctly. That being said I did a 65 mile hike with them and was concerned they would fall out with how loose the valves are. One rig seems constricted like in the Nov. 18th review said. They both have a slow drip when I set my pack down on its side (both purchased bottle and my existing Nalgene). Lastly, the one inlet on the cap doesn’t have a pressure fit rib holding the tube onto it. So it slipped out a lot until I zip tied it tight. It’s one of those things where I still appreciate it much more than a bladder. There definitely seems to be quality control problems and things that I don’t think someone would have sold to me if they just gave it a once over first. If I find something else similar, I will buy it because spending $115 on a water bottle with a hose and an additional hose… should not have dripped at the very least.

Found it to be of good quality. No water leaks. However the bite valve made it really hard to get a drink. Just wish I could get the water to flow more freely from the valve. Finally gave up on it and used my bottle without it.
