I received this at a discount.
This is a great addition to my survival gear, and heck let's face it, my camping gear! I love the water bladders that I have accumulated for putting in my go bag, however, if you don't clean them they get nasty and cleaning them isn't very easy. This makes it easy and makes your hydration bag sanitary again! I am impressed! It is also very compact so it's easy to bring with me either in my backpack when hiking, or motorhome when camping. I definitely give this a good thumbs up!
