Also good for nature and for the wallet.

Despite the many negative reviews I've read on the net, I still tried it, to recap, they are criticized mainly:
- Hang in the machine: in more than a month of use, at a rate of 2/3 coffees a day, one capsule was blocked and it took me 5 seconds to push good with finger.
- To make a lower quality coffee: coffee purchased from the roaster, brewed as necessary, stored in the fridge, and you get a taste at least as good.
- Make less foam: personally, after a decade of trials and different dosing coffee compaction, I arrive at a correct result.
- To be fragile: as a general rule, those who complain of having broken, people have opened them with a knife / hammer / crowbar ... By cons, with a minimum of care and common sense after a month, they function like new.

After twenty use the same capsule, little is observed a slight deformation of the cover, but it does not interfere with the operation.
