Paper filters are maligned for removing the flavor oils.
Detailed Commentary
I actually own two of these - the first one purchased two years ago and another procured just a few months ago.
Our main brewing method has settled back in to the auto drip maker. After a romance with vacuum pots for two years, that apical form has been relegated to weekends only at this point, yielding to convenience. Fortunately our B&D SpaceSaver brews at 198 degrees, so we aren't compromising too much.
All that said, we brew 2 to 6 mugs per day using the Melitta One-Cup. After grinding 2 scoops of beans almost espresso-level fine into the #2 cone filter, I pour water from our kettle (just off the boil) over the grounds. Because I use fresh, home-roasted beans, there is much "bloom" or foam as I carefully pour in the water.
We really enjoy the coffee made one mug at a time like this. Even though the paper filter may be robbing some of the flavor oils, the coffee is always crystal clear (as opposed to French Press) and doesn't seem lacking.
I also have the SwissGold OneCup filter, but find it very stubborn in letting the water through - maybe because of the fineness and amount of grounds. I tend to stick with the Melitta for single mugs of coffee.
Buying Experience
The checkout lady at the grocery store was nice...as I recall.
