I have one and have tried it quite a few times, being very careful to follow whatever procedure I'd been shown. To me the coffee has always tasted burned. But... I buy much better coffee now.
It is fun and I like the ceremony, so I'm going to check out the video someone linked to above.
All I know is, buying light-roast coffee and a proper burr grinder will change the way you view coffee. I even wrote a little app to calculate the exact amount of water per gram of grounds, and then you can enter the total weight of the vessel (intended for Chemex-style pour-over) and a wet filter. It saves that and then tells you how much the whole thing should weigh when you've added enough water.
