Was very excited to get the Sette after in being backordered for months. First impression is it's a bit bigger than expected. That said, it still fits perfectly snug on my countertop next to my Rocket Espresso machine. Next, the grind. The micro adjustment is a nice touch - you can really customize your grind and play around until you find what works. The portafilter arms are nice as well.
Grounds retention - there are none. The grinder is as clean as possible after use - an incredibly nice feature that my wife adores (no loose grinds everywhere after use).
The negatives - It. Is. Loud. As all the other reviews said, I can confirm - It's a noisy grinder.
I went with this model over the 270W since I didn't see myself actually using the dosing technology - I like to do things on my own.
Overall, 5/5 stars. This thing is a beauty.
