Thanks for your quick reply.
I’m not worried about the reliability over time of the thread, I just want to know if it’s the same manufacturer, I practically ordered it from the manufacturer.
I was intrigued by the story behind this coffee grinder and decided to test it.
My coffee grinder is equipped with a 300 watt AC motor and is quiet throughout the entire operating range.
I haven’t tested the alignment of the grinder yet, just used it for a few days. The first coffee impressed me.
I checked the retention, values obtained in grams, using the bellow: 0.5 ; 0.1 ; 0.1 ; 0.1 ; 0.1 ; 0.1 ; 0.1 ; 0.1
After a few shots the coffee was no longer as good and anyway it was necessary to open the grinder to see where the coffee accumulates.
The declumper is double, the first layer is made of vertical slats in zigzag and the second layer is made of a full slat.
I bent the second slat a little to make it easier for the ground coffee to come out and since then there has been no coffee build-up left.
Using the bellow, there is hardly any retention.
