Query: Leaks, clogs, high maintenance, but looks nice

Ostensibly the perfect coffee maker for our kitchen; brushed stainless look, grind and brew, thermal caraf. Oh boy, what a nightmare. We've had it for 5 years now, it has always clogged up, it is very difficult to clean. The grinder mechanism practically welded itself to the plastic chassis, making it impossible to remove for cleaning. Rougly 20% of the time it mysteriously leaves 80% of the coffee on the counter during the brew process. We're still baffled by how it happens, but it leaks profusely during the brew process. This normally happens on Monday mornings ;-).
