Cooling time:
The ice making drinks for about 10-15 minutes cool and takes about 2-3 hours until they are nice and cold.
Color:
After use, the stones but the color change easily in a darker gray tone.
Conclusion:
A great alternative that often distort the taste of the drinks to the normal ice cubes. Unfortunately, you can reach through this ice not quite the temperature as normal ice cubes from the freezer and therefore there is at this point a star deduction. Otherwise, an absolute innovation and a strong buy recommendation on my part :)
