My "Bottled Water"
For me, the most valuable aspect of bottled water is the water bottles, which can be refilled and reused to deliver fresh, delicious tap water whenever you like. These bottles are rugged and last for years of normal use.
My favorite is the "New Zealand Eternal"--I snagged this during a job interview. On the one hand, bottling water in New Zealand and transporting it to North America is--frankly--immoral. On the other hand, since it is so flamboyantly wrong, they supply the nicest bottle!
The "Tropicana" bottle is pretty rugged and has a nice, wide mouth. There is also no ambiguity--if you see me drinking water from a Tropicana bottle then its pretty clear this is some home-refill job, and I'm not some asshole who has to maintain the purity of his bodily fluids by importing water from New Zealand!
