Questions about Severin Yogurt maker with automatic programs

I have only used the time extension so far. I haven't noticed any freely selectable temperatures

The glasses were included. They have a black lid which doesn't seem as high quality to me as another glass set I had from before

Normally it is a Swiss plug. However, if you receive the product with a European plug, you can contact customer service and a mini adapter will be sent to you free of charge (this will not change the use of the product and the plug will be only slightly longer).

(Sweet) components (e.g. syrup, jam, fruits etc.) can be added from the beginning.

The containers are made of glass. You can also use others, e.g. the 160 jars.
