These smell similar to chlorine dioxide tablets. A light chlorine smell that mostly dissipates after you shake and remove the lid a few times. I didn’t notice any taste. The fact they don’t work against cryptosporidium worries me a little, but I’m not sure how much of an issue that is where I typically hike.
TINY and basically weightless. It’s so nice to come back from a backpacking trip and simply throw away the disposable water bottle and be done. Nothing to clean, dry backflush, etc
