Your questions, answered
I read that some units stop mid-brew — is this a widespread issue?
A small number of reviews mention this, and it appears to be an isolated defect rather than a design flaw. Regular descaling and using filtered water can help prevent this in most cases.
Is the coffee quality really that good compared to a traditional brewer?
The Strong Brew option specifically addresses this — it increases the strength and boldness of the flavor, which is exactly what reviewers praise most about the taste.
