Finerfilters Personal Portable Water Filter Straw 3000L | Microbiological Water Purification filter, Ideal For Camping & Hiking etc. (1)

Very good to have. The only thing that is less handy is that it isn't as practical when using it to fill bottles or drink from bottles because it isn't designed to fit into a bottle mouth. This could be a very practical upgrade if applied to future models.

Absolutely useless. Supposed to connect to a water bottle - but the threads are almost completely lacking due to bad quality production. I managed to try it anyway on the tap water at home ... but after a few deciliter it suddenly was completely blocked. Amazon hides well any possibilities to complain so a complete loss for me.

Too big, but otherwise functional and cheap. Won't fit a camelbak though, so bare that in mind.

A handy size for the backpack. Simple to use.

As expected happy with this buy

Seemed to filter everything out no bad tummy a good buy for the prepared.

Keep it packaged till I used it

Great product and much better value than the high street equivalents.
