Filling the capsule is very light after several attempts by the hand. I fill the powder with a small coffee spoon up above into the capsule. However, after every spoonful I press the powder with the back slightly, so that it thickens. Finally I remove the finger, the powder from the edge, so that the lid can be closed easily.
I have the capsules used so far exclusively with the Delonghi Pixie. In this machine, the capsule is working properly: It is easy to insert and without pressure. The coffee flows through lush and without dribbling. Before opening the machine, the capsule falls immediately without binding in the collection container. I can not imagine in any case that the machine will be damaged by the use of the capsule.
For probably the most important point: The taste, the result is very good, but does not quite reach the disposable capsules. Basically, the taste very much depends on the type of coffee used. Therefore, I have opened to compare an original Nespresso capsule and decanted the contents into the reusable capsule. Since the volume of the original capsule is about 10% greater, this does not work completely. Since the powder in the original is extremely finely ground, one must press the not quite as strong when filling the content, otherwise the run is not as liquid. For direct comparison, I still brewed a cup with an original capsule. The crema on the original is a bit more pronounced and the flavor a bit more intense. But this is criticism at a high level and falls on only when direct comparison.
Overall, I am very satisfied, but apart from the very high price (12 for a few grams of plastic ....). Therefore, a star deduction. Time will also show whether the holding quite thin connection between the cover and the capsule was continuous use. So far, however, fits all.
