WS02 Water Filter Straw, Detachable 4-Stage 0.1-Micron Portable Water Filter Camping, 5,000L Water Purifier Survival Gear and Equipment for Hiking Camping Travel and Emergency - 1 Pack

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.

Excelente material de filtragem. Recomendo.

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.

I don't see how you could go a four or less with this product this product is well made and does a really good job couldn't believe how good I was amazed.

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!

Es ist alles in Ordnung, angekommen. Über den Qualität kann mich nicht äußern, noch nicht ausprobiert
