I purchased the earlier version of this Capresso system over ten years ago and just purchased my third one last month. Providing regular cleaning (flushing with vinegar and water) and changing the filters according to the instructions must work as I've never had any problems. The aroma is amazing while the system is grinding the beans. That aroma and the noise from the grinder serve as a great  morning alarm!  My guests LOVE this machine as well. I highly recommend it!!!
