Bests & Worsts Reviews from Amazon

I've owned two conical burr grinders in the $100 price range and they both make a big mess while grinding because of the static electricity they generate. The designers of the OXO completely eliminated the static problem by incorporating three design features: a metal grounds bin, a grounded power plug, and a lower motor RPM. There is a little metal tab at the top of the bay that the grounds bin slides into which connects the metal bin to the ground prong on the 3-prong power plug. This grounds the metal bin giving the static electricity a path to dissipate to. I know the motor speed is slower than my previous grinders because it takes almost 30 seconds to grind the 60 grams of coffee I need to brew a pot. Not only does the lower RPM help to minimize static, but improves the quality of the grind. There are far fewer fines in the medium and coarse grind settings I use. The slower RPM also keeps the metal burrs from heating up as much and it lowers the noise level. This grinder gets a solid five stars. UPDATE 9/3/18: I'm still very happy the grind quality. In doing a little more research, I've found that this grinder has 40mm burrs and runs at 400rpm which matches the specs of the highly rated $230 Baratza Virtuoso.
