Seriously, why choose a copy at the expense of the original, knowing that both are the same price for 1 pre cent (34 vs 35 cents)? The original recycle, Carte Noire does not specify the steps, and even the packaging adds "unnecessary" history of increasing wastes. As for taste, I used to think like colors, this does not argue, but in this particular case ... taste less "racy", less creamy foam ... for a regular Nespressos and variety their flavors, I find it hard to join.
In practical terms, the capsule works perfectly, it normally rises and séjecte.
In summary, for almost the same price, why choose a capsule plastic rather than aluminum, which is not "eco friendly", and whose taste may be poor? Given that the main interest, if not the only one, of these alternatives pods is precisely the price. So before these capsules, it is reasonable to ask ... "What else?" (What else?) Without the nod to go with it.
