Beautiful, functional, simple.  Makes great French press grounds.  Can also be used for pepper, coriander, cloves, allspice, cinnamon, etc (grind rice afterwards to clean it).  Self-cleaning!

Takes a little effort (not sure this is a negative).  Not the easiest to keep it still while grinding.

I am the only coffee drinker in my household, and I use a French press pot.  Once I found the correct setting (using the instructions at sweetmarias.com), this made the best cup of coffee I have ever made at home.  It does take some effort, but not much at all, considering that coffee is a very soft material compared to some grains and spices.  I have the open-hopper version, so if I needed to I could grind at least a cup of beans.  I have never had to grind that much.  The drawer seems to me to hold a lot, but I think it only holds enough for about 6 cups.  So if you are making a whole pot of coffee you might have to empty the drawer once (but will that kill you?)

It looks great on the counter!  It's a beautiful, quiet, perfectly functioning work of art and engineering.  It's great to be able to see exactly what is happening.  If you have kids, this would be a good learning opportunity (and maybe even for your spouse!)

I got the mill at Sweet Maria's.  I got a personal email from  Maria herself when the mill had shipped, and I got it the next day after it had shipped (going from Ohio to California via USPS).  I guess the fast shipping is not her doing, but I was really impressed with the customer service.
