Bought one of these recently (800ml), and it sits in front of me at this moment. Great bit of kit, solid, seals very well, no taint carried over from juice one day to water the next, even after the most perfunctory of cleans. I have also invested in a food canister, good if a little on the small side (or maybe that's my appetite!), and a vacuum bottle. Bought a painted vacuum bottle to see how it all stands up to the 'work in the week, out & about at the weekend' routine.
They are a bit pricey, but they have no laminate on the inside, and are made of food grade stainless. Quality gear throughout as far as I can tell.
