I've used Aqua Mira for several years, overall it's my favorite method of water treatment... my only gripe is the 15 minute wait before drinking. On my recent section hikes I've met several hikers using the Steripen, they all seem to like it. I'm curious on opinons from WB on the Steripen.
some of the pros and cons of Steripen, and I'd be curious on other's opinions:
Pros:
Relatively rapid treament time
Lightweight
No pumps, no chemical after taste
Cons:
Relatively short battery lifespan, and cost of replacment CR123 batteries or AA batteries
Can't use in subfreezing temps
Have to use with water bottles with the minimum size mouth diameter
Must use in clear water, must prefilter cloudy or turbid water
Steripen makes several different models now, including a Mil-spec model that is supposed to be more durable than the civilian models...any thoughts on best model for backpacking?
