This is my first post!
I am currently using an M3 grinder from Versalab on my coffee cart in my roastery.
We do relatively low volume on the whole, but have two to three very busy spirts on the bar throughout the day.
I really like some of the features of the M3 like the two burr sets (conical into flat), the straight through vertical design, and the "worry free" distribution.
However, there are short-comings, like durability of the wiper blade (replaced three times in 9 mos) and the belt drive (belt replaced once due to operator error).
The long grind time is not so much an issue with the portafilter holder (currently 20ish sec), but the reliability and availability of parts scares me a little.
I am considering replacing the grinder...
To the questions:
1. I like what I see with the Robur-E doserless, but does coffee end up sitting in the chute between grindings?
2. Is the Robur-E my best bet, considering the $$$? Maybe a Compak WBC instead?
3. Does anyone out there have any experience with the M3 and other high end grinders above a Super Jolly?
Most of our baristas are still beginners, so it is important to me to have something with a timer mod at least...
Thanks for the thoughts
