With its stainless steel jug, magnetic plastic whisk and simple heating plate, the Caso whisk is a typical representative of the mid-price segment. The four basic functions (see Gastroback) can be called up and started using the Select button. The removable jug froths a maximum of 250 ml of milk, which corresponds to the fill level of the clearly legible MAX mark...

The Inbox differs from the Black only in the colour and material of the milk container. In contrast to the black container, this one is made of high-quality stainless steel. The other features and functions correspond to the Black model.

This model is wonderful for milk foam made from milk alternatives, and it always shows off its appealing quality. The fact that it cannot achieve the same quality with milk is annoying. While the user experience shows some weaknesses, the range of functions is very good.
