I’ve had the duo for just over two weeks. I seasoned with approx. 1kg of beans, and I’ve been pulling two shots daily.
So far so good, but too early to compare with the Zero in terms of taste. As I’m not interested in filter, it’s only used for espresso. So far my observations have been:
- it’s louder than the Zero, to the point my family have made comments. They never said anything about the noise of the Zero, but the Duo is louder. The fact the grinders are side by side on a solid oak sideboard with a top which is 2cm thick and grooved inside - rather than a kitchen counter top - amplifies the noise considerably.
- I’ve just taken the top burr carrier today out to inspect. The threads are as clean as a whistle. The original grease is still there, and I have not brushed the threads or anything as it’s just clean. I have not seen any stuck beans or fines on the threads as reported by @LMSC.
- it’s harder to dial in compared to the Zero. But that’s just expected, as it’s a flat burr grinder and those are more sensitive to adjustments. I was drinking a Brazilian single origin from Wogan, medium dark. 7.5 on the Duo, 20 on the Zero. I’m now drinking a Kenyan coffee and it’s on setting 4.5 (a tad too slow) but I think the ideal will be 4.75 or so. It was flowing way too fast on setting 5.5. Bottom line, on the zero one would adjust in terms of full marks. On the Duo, it’s in terms of quarter and half marks. Update: 4.75 on the Duo, 14 on the Zero.
