Negatives:
- Looks so sensitive that you do not dare to put them in the dishwasher;
- The edge of the neck is "cut off" (not like drinking glasses rounded), which here and in some of my vases leads that in light bumping immediately chipped to the tap some of the glass and also speaks against the SpüMa;
- At the price quiet a second, firmly closing lid because of carbon dioxide and flavor (water must not always be pure) should additionally be going.
ADDENDUM:
Meanwhile, there is a lock in addition to buying.
