These worked fine. People were saying that it was hard to get the water through, which I disagree. The first suck had to be strong, but after that, the water came through pretty easily. If you're filtering water to the level these do, you can't expect it to be like a normal straw. I bought four and they all worked. Just don't forget to flush them when you're done so they last longer!

I bought this as a safety gift for my boyfriend since he likes to hike and camp a lot, and it has worked great every time we have used it!

Although this is survival equipment, it is also just fun to try it in a fresh mountain stream. Super cheap and potentially life-saving item!
