Bests & Worsts Reviews from Amazon

The only concern that I have is that the flow rate is a bit slow Considering the size of the unit it is understandable. I did run a bacteria test with raw water from a mountain stream that was pretty clear. After incubation the raw water did show evidence of bacteria growth (photo attached) but that same water through the Sawyer Mini showed no evidence of bacteria. I also used a Steripen Classic 3 on the raw water and saw no bacteria growth. In this limited test both products seemed to work well for bacteria. That gives me confidence using either of these products.
