I have not used it yet
I have not used it yet. If I use it it has a five year life span. I don’t see having used it and 1 or 2 years later having to use it the water that passed thru it there is some that stays in the straw for 1. Or 2 years and to me would cause bacteria etc in the straw. Is there a way to avoid this? But I am glad to having in case I need.
