I haven't gotten any yet but I really want some.

As far as storage ... make sure you use a container that's all glass, or glass with a metal lid - no plastic. I store lots of dry goods in jars, and neither the screw-on polyethylene tops nor the polycarbonate pressure lids are moisture-tight. Supermarkets around here have the hinged-lid glass jars.

And has anyone tried their SiO2-lined water bottles, or have any contribution on the science behind them and their likely durability? I'm very curious.
