This is something I believe that everyone should have. It is super convenient as a small, easy to use water filter. It is super smooth with dispensing the water and doesn’t require much effort at all. This is intended for just for emergencies, but I have taken this fishing and drank straight right out of the river it works amazing. I honestly found it easier than lugging around a bunch of water, as it can be compacted for easier storage, even in your own pocket. I honestly have nothing bad to say about this, I highly recommend.
