The dispenser makes a qualitatively good and stable impression. The portions are not very large and varied. One serving equals about 2 teaspoons (about 8.5g for iced coffee powder). Have the time being a dosing ordered for testing. Wanted more for baby powder, Dishwasher, Washing powder and coffee. But can not really use it, as the portions are just too big. In addition, the "ejection-area" very large. When a baby bottle or container washer some would go next. In a normal drinking glass one is just so fail. If there were the dosing smaller with smaller portions (max. 1 teaspoon), gäbs 5 stars from me.
