Have these capsules for a new Krups Nespresso Maschiene bought which I will use in Thailand and the purchase of filled capsules is there virtually impossible. For sample I ground coffees and finally achieved reasonable results. Basically clear signs of use, these capsules work, however, have already after a short time. The filling and the right grind is a matter of practice and dependent on coffee. One must keep trying until the result satisfied. A longer shelf life of these capsules is very questionable and I have therefore ordered another pig expensive stainless steel. Who does not have to pay attention to the extreme price is better off with finished but twice as expensive capsules.
