Fresh water for one person

Hear about a video on this product, I ordered it to me. For the next trek in the Palatinate Forest 3 days Here also the filter equaled used.
When I look at the positive
- The very low weight
- The very simple use of the filter
- Is it easy to clean
- The optional "straw", by which one can be equal to drink from a water source

Time consuming it was to him, the water for 2 people to filter even on stock. The sources were sown sparse, so we wanted to take every 2-3 liters of water. The creek was not very clean. Some of coarse and larger suspended solids were found in the water. Therefore, we wanted to filter out the water with a handkerchief.
In the small opening of the plastic bag to put the but as a larger Hinterniss. We were able to solve it, but
it kept us on time pretty.
But I think the filter is not necessarily made for water for two persons and then to filter on stock. Rather a person, right at the source, and some are on the go.

Conclusion: For one person, the filter is ideal if you do not depend on a lot of water to filter (there are even more water sources) or the mum, with suspended fill contaminated water directly into the bag and then filter. The fumbling with handkerchief and bags kept us on too long.
Because of this cumbersome procedure, there is a point deduction. Still, I can recommend this filter bisherher.
