I switched to the first gen F4E Nano from a four year old Baratza
Vario that was on its third repair in 6 months.
The F4E is built incredibly well and looks beautiful. There is some clumping of the grinds, but not much. There is retention, 2-3 grams at least, which one can live with.
Adjusting the grind is a two handed process (ideally 3 handed), but I don’t find myself adjusting more than once a week or when changing beans. Most of the time I can get very close by eyeballing the beans before pulling the first shot.
I occasionally will grind coarser for pour over, but this is not a joy on this grinder. It’s really suited for espresso. Adjusting to a courser grind may require one to unscrew the screw on the adjustment ring.
I was surprised that my burrs needed to be replaced after 2 years (about 100 lbs of coffee). I don’t have the best cleaning regimen, so maybe that is to blame. I also home roast, and maybe missed a pebble in the beans.
Overall, I’m very pleased with the grinder for the price. In the future I would look for something with less retention.
