Yup. Both the Vario and the Forte have flat burrs.
The other models have conical burrs.
But, all of this emphasis on Customer Service makes me think sticking with the MD-50 is a better idea for me.
I don't want a grinder that NEEDS customer service....:-))))
Still.... that Forte is tempting. I'd like to spend less time weighing, sweeping, re-weighing, and still having to add or subtract grinds before the brew....
On the other hand....a bird in hand....
Dither dither dither....
