Qunlei Bottle Filter Replacement - Personal Filter Straw for Hiking Camping and Travel - Survival or Emergency Filter

Good water bottle, and well made. I can't see the plastic one touch lip opener lasting a long time though. Water taste good, takes that nasty taste away. Not sure why a clothing manufacturers is now turned to making water bottles though. That was a bit of a shock? Keeps mentioning award winning technology, but no specific awards have been mentioned. I have noticed since using the bottle it leaks. Not so bad if doing sports, really annoying when you've got your suit on.

This bottle is useless - like other reviews I found it almost impossible to drink from it as water would not draw up through the filter - if there is some ‘knack’ to getting it to work then it should be included in instructions. There is nothing! Returning for refund.

Could not drink its locked, poor quality

I bought this before our India vacation. Thought this would be perfect for my little kids and perfect size. 1 day before travel, i filled water to test and could not suck water through filter. Spent lot of time trying and blowing air etc..finally it worked somehow and got smooth flow. After few hours, same problem, water is not coming through pipe and some kind of air lock keeps happening every now and then. There is no way kids can use this regularly, even adults can't use this regularly. There is no one trick to make the flow better. Horrible filter and product. Now i am back from vacation but no return option now :(. Disappointed!!

I like that it is small and you can hook this to your backpack. I am an adt who uses this.

Does not filter toxins found in tap water!
