Likes: Fits all of my water bottles and bladders.

Dislikes: I have no dislikes

Reviewed by John M. - September 21, 2010

Likes: I liked the small size. Not hard to use push once for 1 litter wait for light to bling swirl around until light goes off. Does not change the taste of the water and when you are drinking from a cold stream water doesn't get any better. In fact when I got back to my truck I had a bottle of water there but chose to drink the last liter of mountain fresh Steripen water. It filters water for four and for three days on original power.

Dislikes: Inconsistant. On more than on occasion the light came on and went off in under fifteen seconds. I just started again. Could be user error pulled out of water or something.
