[at-l] Steri pen water purification

[Charles W. Davidson]

Hi Gang,
            I just got back from a 6 day hike. I tested out my new 
Classic model Steri Pen that I purchased at REI. I sent the faulty 
Journey model steri pen back to Nitro-Pak for refund. They said that 
they found nothing wrong with it so I ended up paying shipping including 
the initial free shipping. The gadget worked periodically ( I just 
retired from 36 years at Corning where I repaired electronic 
instruments). Counting shipping and all cr123 batteries I purchased 
testing the thing it cost me a bit. I should have gone to REI in the 
first place and I will not use the other site again.
    But now I am happy with the Classic model Steri-Pen. It uses AA 
batteries and will clean twice as much or ~ 100 liters of water on 4 
lithium AA's. I get an 8 pack Lith AA at Walmart for <$10. which is the 
same cost as 2CR123's. It seemed a bit odd purifying the same water 
sources that I have drank from for many years. However it is so easy and 
quick that I really did not mind the 90 second wait for each liter. The 
device worked will with standard size small neck soda bottles or large 
mouth (my preference). Large mouth do not freeze up as fast as the small 
ones. Both store better upside down in cold weather because freezing 
starts in the air gap on top.
