nice for emergency back-up

As reported in other reviews, it takes some work to get to purification level, but it can be done! The trick is to keep going for 90 seconds no matter what, set a timer so that you go the whole way, and like magic it releases and is done at exactly 90 seconds. I am a 66 year old woman and was able to do it once I learned the trick. My only complaint is that the regular water bottle top leaks like crazy. I am going to write to steripen about it and see if I can get a new top or bottle replacement.
