Query: depends on what coffee you use

The performance of this item depends on what coffee you use. I purchased it and used the same coffee I had before, and it made the same crappy coffee that my coffeemaker made. Then I bought a jar of Illy moka coffee at Sur la Table, it's expensive ($15 for 8.8 oz) but it made a world of difference. When I use Illy it makes very good coffee. The 3 cup size makes a small cup of coffee (about 1/3 of a mug) but very strong.
