I own a Wiggy's SS bottle. Solid design and execution; except I replaced the lid attachment chain, that I thought was a weak design, with a SS "clock" chain - unbreakable! Very well thought out bottle - over engineered maybe (read: weighty) - but when I'm in the big woods, by myself, and want something to keep working for a long time - well. . .. Lid seals with a gigant-o o-ring so be careful if you heat the water - it might just explode. But I like the whole setup since it gives me another way to sterilize and heat water that no other water container really gives me. I "don't leave home without it" anymore!
