Static is my enemy.
I recently modded my Mazzer Major with a funnel. Along with all of the convenience of no longer having to deal with a doser, I am also experiencing the torment of a new sort of problem- static. To sum up the problem, when I turn on my grinder, the grinds stick to the side of the funnel and do not drop into my portafilter. It is a pain, and worse, it causes a whole lot of waste.
