In concept, I would give 5 points for transportation and price. I have bought this cereal-to-go cup for me every day is my muesli with fruit to take to school. And for that he is super, with milk it works great (it runs from nothing), with milk you just have to make sure that you zuschraubt the cup firmly! Only 3 points because he is a bit too small for my use. For example: 1 medium-sized apple with muesli, it fits very well, however, so that the maximum capacity is reached. For someone who likes 2 different fruits entrains it is clearly too small!
