Bests & Worsts Reviews from Amazon

So I'm testing a few water purification methods for a backpacking trip I'm leading next year around the TRT. This bottle is my first experiment and I received it yesterday. I opened the LifeStraw Go bottle today, read all the instructions and followed them explicitly. I admit to being nervous as this filter is not fine enough to filter viruses like the bigger LifeStraw filters and some other brands of water bottles. As such, I will not give the bottle more than 4 stars without that capability. In any case, I stopped by Lake Topaz on the California/Nevada border, scooped up some water and sipped it down over the next couple of hours. I'm writing this now 9 hours later and feel no ill effects as of yet. So far so good LifeStraw Go! After reading so many other reviews, I was skeptical about the suction required to drink and the fragility of this bottle. 1 ) suction: I admit I'm surprised at how easy it is to drink from the straw. Although the flow rate might be a little slower than my camelback straw water bottle, it's not a significant decrease. I've got to say, I really don't understand how this is a complaint unless some people are suffering from defective filters or user error. 2) Fragility: The bottle seems sturdy enough so far and although I haven't smashed it against anything, I did gently knock it around with no damage. I plan to use it daily to drink from the mountain streams out here in the Sierra Nevada mountains over the next few weeks and update this review as I go. Update: So I dropped a few stars on this product because the flow rate decreased to zero after letting it sit for a few weeks before picking it up again. I imagine it would probably have continued to work had I used it daily but as I don’t live in a third world country, I only need it periodically. If I have to buy a new filter for every time I want to take it hiking or camping, it isn’t worth the cost compared to other options on the market.
