At first a little surprised that the carafe is made of plastic (product description is not read properly), to have my fears, such as that small pieces of lemon slices could damage the material, but not true.
The closure seems to be very good. It drips anything, it can fall into nothing and end up (if you are lemons in the carafe) no seeds in the drink.
The cooling element keeps the drink cool. Hot drinks are not far cooled down at high temperatures, for the cooling element is also not intended.
Would the carafe buy again at any time.
