So as not always having to rely on plastic bottles, I have bought this bottle. A feature particularly worthy the drinking spout, which is neither too big (Schwipp-slosh effect) or too small (Babyflaschen.Effekt). The bottle holds far too well sealed, in a purse, backpack in, horizontally or vertically standing, the water stays in there. With a capacity of 800 ml has also always enough without, to feel as drudge like standard 1.5 liter bottles. The only downer after about 2 weeks peels off the outer coating of the bottle, admittedly I have the bottle is usually outside of the backpack in a network. But larger events or otherwise disagreeable, she had not yet survive. Hence the surprise "Lackschaden" me a little. DieFunktionalität does not affect the.
