      I bought one of these for using while I'm flyfishing so that I don't have to carry a bottle of water with me. It is perfect for that use - I just scoop up some water and have a drink when I need one, then fold this back up and tuck it into my pack or clip it to the outside of my chest pack. Unfortunately on a recent Flyfishing trip that included a lot of hiking, I found that when I made it down to the river, the filter and cap was still attached to my carabiner on my pack, but the bladder was gone. I reached out to LifeStraw to see if I could buy a replacement and they sent me an entire replacement unit for free! Talk about great customer service. This is not my first LifeStraw product and it definitely won't be the last!

      The plastic taste is overwhelming. I’ve followed the instructions, but cannot get past the extreme plastic flavor. I have flushed it and rinsed it over and over with both fresh water and saline. It’s unpalatable, and I can’t imagine that it’s safe.

      The media could not be loaded.
      The filter does the job but it came with a tiny puncture and the flush cleaner is not tight enough to make a seal and actually pull water through.
      Also, how do they not have a version for european bottles?

      I haven't had any problems with the taste like many others seem to.
      Overall it seems like quality assurance is pretty lacking on the collapsable bottle version, but the filter inside works just fine. Filled with lake water multiple times and no effects 1 week later at least.
