Came from a Breville Smart Grinder Pro to my first flat burr grinder. I can immediately tell the difference in my pour overs. They taste sweeter and I can tell different notes. Espressos seem richer and seemingly more syrupy. However, the grind settings drifted a bit at the first few brews. Had muddy pour overs. Could be because of the break-in period. I did season over 2 lbs of Kirkland Organic Peru before my first brew. Didn’t want to waste my “good” coffee in the process. I don’t know if I need to align my burrs or not. I hear chirping when switching settings. But, I could’ve messed up the alignment by taking the top off to see if they installed my red titanium burrs and not paying attention and being a rookie and just putting it back without knowing which position it was in. I got this to learn flat burrs and maybe upgrade to SSPs later in life.
