Hi there We use a variety of pods in our Nespresso Creatista machine, including your Brazilian blend No11 and Mocha Italia blend No5. We also use Nespresso and other brands. When using your pods, the machine struggles to pierce the foil covering, sometimes not piercing them at all We now have approximately 8 boxes of Costa pods which are no good and have not used. We bought them from Morrisons as they were on offer at £2, reduced from £3, but now we wish we hadn't, as the last two boxes have contained several duds. I notice Costa seems to be part of the Nestle group, so am surprised they work so poorly with our Nespresso machine. We have not experienced this issue before or since with other brands. Maybe this is a batch issue. I would appreciate your feedback Thanks Richard Stinton
