Product review (5 stars): Feeling safe and cozy. Pun intended.
I am really impressed with this product I have two of them now and am pleased with the small size and portability of this straw. I plan on giving one as a gift and putting the other in with my backpacking gear. I have the water bottles with a filter that claims to do the same thing as this. It however takes up too much valuable space in the back pack. These would be great in Illinois where the city gave all those people contaminated water. That would be a great test for these. I plan on using this with my flatten and roll water flask or if need be get down and drink right out of the stream with this.
