Query: Makes the worst coffee I've ever had

I cannot imagine why so many people like this coffeemaker. I have made 12 mugs of coffee with it over the past 4 days, and even though I used DOUBLE the amount of beans I normally use, the coffee comes out very weak every time. I tried various grind settings, but they made no difference.Other things I hate about this unit:- You have to clean it after EVERY pot of coffee because it has a permanent filter (thus you can't just pull the filter/grounds out). I make 1 mug of coffee 3 times a day, so I have to clean it 3 times a day!- The permanent filter allows some of the grinds to end up in your coffee, which is unpleasant.
