Query: Great One Cup System

This coffee press produces smooth, even flavored coffee, and is a breeze to clean. It now has a permanent place in desk drawer at work, and I may need a second one for home. Perfect for the office, as it's much easier to clean than a French press. It takes a little tweaking in terms of experimenting with how your favrite grind / type of coffee works in it, but well worth the initial investment.
