I have a several year old nespresso machine, and these pods fit in the little slot at the top, but the machine get's a little confused using them, and 8 times out of 9, spits out a fraction of the water you asked for, before gobing the pod into the bin and flashing all it's lights. So maybe it's just older models of machine, or maybe it sense's the 3rd party coffee pods. Either way, just be aware these aren't official Nespresso coffee pods, and all that that implies.
