It must be said clearly that the cube of the cooling capacity can not get real ice zoom ..
but that's probably because the dice cast their temperature to the liquid and thus are outside warmer inside but further cold.
ice melts, however, and thus is always the coldest layer outside and is of no warmer layer to drink is shielded ...
I can understand the disappointment because of the cooling capacity compared to understand ice, but can not understand why you have not strained his brain before buying !!!
Who wants ice cold drink must remain with ice cubes
