This is my first coffee grinder. After reading many positive reviews I decided to purchase the Rhino Tall Grinder. I wanted a fine grind for my espresso shots and I can confirm this grinder fits that purpose. I’ve used it with dark and med roast beans and does a fantastic job. With the different beans you get a great feedback as your grinding as you can actually tell if your grinding a dark roast beans to a lighter roast bean. My way of getting the grind size is for dark roast screw burr nut fully closed then turn out 2 clicks and turn out 3 clicks for med roast beans. Build quality is solid and dismantles for cleaning so easy. Once ground the grind cup fits lovely into my portafilter and emptied with no spoilage. I highly recommend the Rhino Tall Grinder at a great price.
