good for when you need water and are in a pinch
I was out in the forest, lost, cold, and scared, when I remembered watching one of these great advertisements for these. I quicklyy grabbed my phone and had amazon use one of their new drones to deliver it to my exact location. because of the amazing technology used within this tech, I was able to survive off of my own urine and a local muddy puddle that I became good friends with out in the forest. by the second or third delivery from amazon, it occurred to me that I should just return a package with me in it so I could make it back to safety. besides, I was getting a little sick of the urine infused water, and also there was a bear. he looked a little hungry to be completely honest. I may also have been really high when this all went down, but great product nonetheless!

These work very well. Use it with my base camp 4L gravity set and the everything connects no problem. Filters quickly. When it slows, a quick back flush and you're back to normal rate. Best part, no beaver fever, diarrhea, or dysentery.

Straw is working perfectly. It can be fixed on to Mai Dubai’s water bottle. Remember to remove the cap locking ring on bottle neck before fixing the filter straw. Water flow is not too much but it’s more than enough to survive. Very useful gadget to have camping, trekking and travelling.

Love these, we take these every year back country camping, drinking from lakes and rivers, clean and purify water so well. Water tastes better than from a tap!
