I've been using my new Vario for a couple of weeks now and I really like it a lot. Pluses include:
-the number of grind settings (it's not stepless; but 230 choices gives me plenty of options). The grind is actually noticeably different even when changing only one "micro" notch.
-the eveness of the grind - I didn't scientifically measure but the particles seem to be the same size.
-neatness; no mess on the counter, also no waste - what goes in is what comes out. If I put in 17 grams, I get 17 grams out.
-consistent results, I've pulled some really good shots, had excellent pour over results, and good drip coffee all with one grinder.
- grinding directly into the portafilter is a nice option (adds to the neatness above).
- Sound - not a big deal to me, but the wife noticed that it grinds more quietly than Rocky.
-Presets are nice, but I'm not sure how much I'll actually use them. I tend to use different coffees for espresso and drip, and don't want to fill, unfill, refill, etc. when I change. I've been measuring on a scale and putting the amount I want to grind right into the grinder.
- Footprint. It fits nicely on my coffee counter and looks good.
The only negatives are really minor. Putting the portafilter into the holder (it goes under a hook) and removing it is a little annoying. Also not optimum because the portafilter for my Pavoni is a different size than the one in my Sylvia. I may just remove the hook and hold the portafilter by hand.
I notice a little static when grinding into the container. It's not a major, but I did need to brush out some grinds once or twice.
All in all, I think this is a great product and I would recommend it highly.
