Aside from pairing perfectly with Wendougee, this is one tough little scale. None of the constant h2o errors you get with Acaia Lunar if there is a drop of moisture anywhere in the kitchen, and you can no longer shut it or change functions. i have spilled boiling water on it (accidentally) and it kept on ticking like the energizer bunny. A no brainer.
So far the grinder is performing perfectly! I love it!
I have had these burrs for one month. They do a terrific job. However, they are wearing out. I have to set my grinder finer and finer and am now on my finest setting.
SSP burrs are typically rated for 10,000+ pounds. It sounds as if you need to perform an alignment, or possibly you have already run 10,000 pounds of beans through them.
