Promising review: "I've used my wide-mouthed Nalgene for EIGHT years, every day at every job I've had. We were inseparable. All the lunches we had together, the late nights, early mornings, fears of bosses, laughing at co-workers...ah the joys we had together. I didn't even treat it that well, dropping it on concrete, down stairs, throwing it in my car, and not a single leak. One time I threw it in my car without the lid on all the way, and it reminded me gently with spilled water that I needed to tighten the lid. I've left it behind almost everywhere, but we always found each other. Until one work meeting when I left it in the conference room. I'm guessing someone grew quite jealous of our affection, and swiped it! NOO! Truly an end of an era. There really was a connection here. Well eight years of daily use later is a good enough review for me to come back and buy the same water bottle. :)" —amznbuyer
