I use this one, works great although in retrospect I should have bought a normal glass not plastic pitcher, just easier to clean. I just use the coarsest grind possible, zero problems...of course, I am simply making paleo coffee with mine (whey, butter, coconut oil, cocoa, 1 raw egg) and guzzle it down in one gulp, rather than sipping it like a gourmand. :D
