The sizes are not correct:
Length 16.5 cm
Width 13 cm
Height 21 cm (stated correctly)

By the way, I am thrilled with it.
Very very few plastic parts in the water, pretty design, good quality and practical functionalities.

Rather small. 1l. In addition, the operation is not great. The gastroback is less stylish but 10x more practical.
