Jura-Capresso 13187 Impressa E8 Super-Automatic Espresso Machine, BlackI have had three of these machines, and most recently bought two so I would have one that would function while the other was being rebuilt. Even that was not enough since both are now non-functional and I am using a Bosch. This machine is superb, easy to use and produces excellent espresso when it works, but it fails quickly. During a two year warranty count on sending it back at least once. Otherwise buy another more durable machine. Now there are some excellent Nespresso choices that eliminate much of the grinding problems that seem to destroy the Jura machines so quickly.
