I was given a selection pack (Espresso, Lungo and Decaffeinated) as a Christmas gift, bought from Amazon.
I tried the Lungo pods in my machine this morning, and the machine really struggles with the pods. When I selected the Lungo button on the machine, it delivers approx 30% in terms of volume compared to what I would expect from a genuine Nespresso capsule. After selecting the Lungo button again, followed by the Espresso button, I did manage to get a cup of coffee that approximated in volume to that I would expect from a genuine pod.
In terms of flavour, I would say that it was good enough. To be honest, as I share the coffee machine with other work colleagues, I don't relish the prospect of standing over the machine and having to cycle the coffee machine multiple times in front of them to get a decent cup of coffee.
I shan't be investing in any further purchase of these pods.
