SP-SYS SteriPEN Classic UV Water Purifier with Pre-Filter and Nalgene Water Bottle
Product Review (submitted on October 28, 2012):
I drink lots of water and find this product very handy when traveling in the kinds of places where guide books warn you to be cautious brushing your teeth. It is easy to zap a glass of water at a time in a restaurant or treat a quart and refill a bottle to carry with me.
