Query: Salt and Pepper Grinders

The best salt/pepper mills! They are sooo much easier to fill than the mills with the tiny screw on the bottom. And, these hold much more so you don't need to fill them as often. I also like that you get a little tray to hold the grinding residue. Only downside, I wish they made them out of something more elegant than plastic (which is why I rated a 4 instead of a 5).
