In and of itself, a really great bottle, but if they are not transported bolt upright and zb.aufgrund a drive inevitably to (slight) comes shocks, has nine times out of ten cases, guarantees fluid loss, regardless of whether the bottle is now full to the brim, or (:-) would more firmly adhered) they are only up to the narrowing füllt.Zwar not much, but enough to get spots on various spills and (juice) to ärgern.Und yes, I screw the bottle firmly to! With the drinking spout reduction (to be ordered separately) the way there the same problem! With a bottle of this price range you can actually may expect absolute tightness! On the basis of this offense from me it only 4 out of 5 *.
