Bests & Worsts Reviews from Amazon

Coffee was fine but a little on the harsh side (not as smooth as Supercrema). Then this rock made its way into the grinder of my super automatic. The grinder is powerful but no match for this. I didn't want to disassemble my machine at 6:15 am but had no choice. Hopefully my gears don't start slipping. I can see no reason why a rock of this size makes it through their process. If this is normal and I have to inspect each bean going into my machine, I'll buy another brand.
