Reliability accounts are split rather than settled. On the positive side, one owner ran over 60 cups in a day with no trouble, another has used a DE1 Pro daily for 4 to 6 shots since last year without a single issue, and a third has had a DE1 Pro since 2019. On the other side, owners describe needing to debug the machine from time to time, mainly Bluetooth scale and tablet connectivity dropping out, and several who otherwise love it name that as their second-biggest annoyance after the tank.
When something does go wrong, owners lean on the Decent community forum, which they say is quick to help diagnose and fix problems. Beyond that, long-term accounts here are thin: a handful of owners with several years on the machine, most of them positive, and not enough hardware failure reports to say what breaks or when.
