Query: Worst machine I've owned

In reading the positive reviews from other owners, I had to double-check to ensure that I owned the same model that they do. This machine spills coffee grounds and coffee everywhere during the brewing process. My wife and I have tried different grind settings, cleaned out the basket and pot lids, and every other thing a reasonable person would consider. Despite all efforts, the flow of coffee during the brewing process completely overlaps the basket and spills all over the place.
