Question: Is this system better than Camelbak which has BPA free tub?
Document: A bottle cap, and a badge clasp made it even better for free. I also spliced the hose so I could put an in-line filter (Sawyer Inline Adapter) and this makes transitioning from one hydration system to another seamless. It weighs close to nothing  and makes it easy for me to go from hunting & fishing, to disaster relief & mission trips by simply unscrewing from one system and moving to another.
I'm ordering my second set of tube/fitting/bite piece so I don't have to swap out a bottle at the top. Has been terrific for hands free/hassle free hydration.It's perfect for the day hikes that I use it for. Can't speak for others' uses.One drawback:  sometimes the fitting comes unscrewed due to jostling during hiking and I end up with a soaking wet toush. Except for that (and I just screw the fitting together better) it's awesome.
Blue Desert's customer service is also very fantastic - I lost the little silicone pressure valve from the cap, and all it took was an email to their customer support to get a replacement. I've been very happy with this hydration system, and would recommend it to anyone that wants a combination of a water bottle and a camelbak-style drinking tube system. Perfect for backpacks!
I considered buying this because I am a quadriplegic and it was a hassle to be asking people for a glass of water constantly at all hours of the day. I decided to get this because it's easier to maintain as well as easy to replace the bottles that I use that originally come from soda that we purchaseIt's economical, and hassle free
)The only reasons I don't give it 5 stars is because of the plastic taste in the beginning, and I'm inexperienced with these devices and there are so many on the market- there could be better ones out there and I wouldn't know, so this is room to move in case :)
Come home from montain biking, unscrew the bottle and pitch it in the re-cycle bin. Flow some hot water thru the hose and DONE! Can't believe that Camelbak has not jumped on this concept.
i wanted something that I could just place over a bottle and take it with me without having to place the bottles whats in the bottle in a bladder . This worked out for me and I love it ,only wish that it had a better clip to secure the long tube more securly to my backpack
Then just tuck the bottle in any outside pocket of your pack, and you're good to go!.Adapters have air inlet valves built into them, so the bottle doesn't collapse while drinking. Good design feature.I'm very surprised Camelbak et. al. doesn't have this.
There are many times when I already need to have a pack on my back, and the Camelbak/Platypus packs won't work. Or I don't want the expense or trouble accommodating a hydration bladder; I just want to use my nalgene water bottle without having to pull it out.Enter, this product!It works just as advertised: it gives you the convenience of a Camelbak but with using a rigid water bottle.
Thought I'd try this for my Camelbak because I hate the chore of cleaning and drying the darn bladder. Used it with a quart bottle, and really liked it. The bottle fits right in the bladder section of the Camelbak. It is a bit harder to suck the water from the bottle as the cap vent is kind of small. The caps are universal and seem to fit all the bottles I use. The cap threads are a little short making them slightly difficult to start the threads evenly.
Answer: yes
