Have used this to grind 3 pounds of coffee.  It is quieter than my previous Cuisinart grinder which broke after three uses.   I use this to grind for a drip coffee maker and the grind is very consistent.   Static is always a problem with burr grinders but this one is not too bad, compared to the Cuisinart. It has a glass receptacle with a rubber grip ring, which is very handy when you are moving the ground coffee to your coffee maker.

Pros: quiet, consistent grind size, less static on the parts which makes clean up easy
Cons: none so far
