These capsules work fine in my Nespresso Pixie machine.
The equivalent in the Nespresso range is Dulsãu do Brasil. This is also similar strength to Capriccio and Livanto.
The coffee is very mild, thin and lacking in flavour, resulting in what I thought was quite an anaemic shot. That is of course a matter of personal taste, but I found the Nespresso equivalents to have fuller bodies with a similar flavour profile.
I've knocked one star off because I consider these to be over-packaged compared to genuine Nespresso capsules.
