Big PRO - used nespresso since 2000 and on my 4th or 5th different machine.

Produces consistent quality espresso quickly - what more can one want in the world?

Was very pleased to find Nespresso machines in the Marriott timeshare properties in Europe - was then very disappointed (after we purchased one of their properties) to realise that this was not standard equipment across their timeshare properties in the rest of the world

One note - I have managed to have bad nespressos (albeit very occasionally) - my firms office in SF had nespresso machines which always managed to produce consistently lousy coffee, and a nespresso machine in a hotel in Zermatt was also not to the standard I expect.

Having said that the experience in terms of quality vs the investement in time and effort is outstanding - just remember these machines do need to be cleaned/descaled at least occasionally.
