It is white at the back - a plastic cover that can be removed for the purpose of removing the glass bottle.

The height is 42 cm. In addition, some height is needed for operation. I was supplied with a CO2 cylinder.

The difference lies in the material of the housing: - Source" has a plastic housing. - Source Metal" with metal case - Source Blue Metal" also has a metal case and is a limited special edition in Switzerland.

The bottles are plastic with stainless steel lids and bases. As I understand it, the glass carafes do not fit this appliance (only Sodastream Crystal). By the way, the two bottles that came with my product are of different shapes: one Galaxus item no. 5597050, the other 218997.
