CamelBak BPA Free Water Bottle 32oz

I've had two of these in daily rotation (multiple fills per day) for several months. They're great except they're nearly impossible to clean. They quickly developed the smell and taste of mold, and difficult to clean areas started to build up material. The minimal amount of cleaning to actually get to these surfaces requires removing an internal tube which cannot be reassembled without tweezers and is easy to damage. Deep cleaning requires destructively removing a plastic pin, a step that's actually quite dangerous to the user. This enclosed area has no light, gets wet, and is in the path of air intake: in other words, a breeding ground for mold that leads straight into the container and your mouth.One of them is already damaged due to light cleaning, and I expect the other will follow in the next cycle or two.It makes me really sad because they're otherwise excellent, but unless the design becomes easier to clean, next time I'll get something without a bite tube.
