Query: my mistake

The role of Amazon in the purchase and delivery of the coffee grinder was, as usual, smooth and efficient. The coffee grinder was branded Cuisinart, a brand I have trusted and respected for many years. This particular grinder does not live up to the reputation of Cusiinart. The instructions claim the grinder can be set for fine or coarse grinding. Not so. The most coarse is roughly equal to "regular grind" coffee, and there is a lot of coffee powder so fine that it adheres to the sides of the receptacle.This grinder performs roughly as well as the cheapest spinning blade coffee grinder selling for $19.95. Does anyone make a grinder similar to my manual burr grinder, but electric? This one is not it.
