So far so good.
Don't think I have the weight calibrated, how currently set it for 18g and get's about 2-3g within.
Could never quite understandable the importance of grind consistency until i got this.
It's a bit loud, but 18g is about 6-7 seconds you're done.
Another amazing thing is the portafilter holder.
I always had my eye on the mignon specialiti and the 270wi, i got lucky with this one on gumtree.
