2009-06-25 Update of review:
Meanwhile, I have the Wassereisbereiter since about 13 months (of which 6 are in continuous use) and I'm still very satisfied. (Why upgrading my rating to 5 points)
Tips for use:
1. When filling Silikonbehaelter easily zusammendruecken (makes room for cover which hermetically closes)
2. Do not fill juice higher than 1cm-2cm below the edge (otherwise something goes juice if you carelessly closes)
3. Before eating Keep container briefly under warm water. (Then it popped out without resistance)
4a. for cleaning without dishwasher:, rinse a) either immediately after eating or b) put in cup with hot or boiling water if residues are dried
4b. with Dishwasher: simply clean it :) opening down naturally
Notes to 4: It is silicone, so keeps sharp objects not at stand whereas temperatures up 200grad not be a problem. (Boil why and dishwasher fold outstanding)
Particularly useful are tough juices or nectars with high Fruchmarkgehalt such as banana or peach. (Which are then frozen softer than clear juice)
