Query: Black & Decker DCM18S Brew 'n Go Personal Coffeemaker with Travel Mug

Although the coffee tastes good, this is not a satisfactory product & it creates a mess when you use it.Specifically, during the filtration phase the coffee grinds spill over into other compartments of the coffee maker & some even land up in the coffee cup.I prefer to use my old-fashioned 6-cup machine & paper filter with the coffee going into a carafe.
