Works perfect from what I see. The paper filters drain so slow the filter fills up and can overflow. It makes a mess inside the machine and there's grounds in the coffee when that happens. I tried the reusable filter and it drains so fast that the coffee doesn't get wet around the edges, just in the middle where the spout is. It's crazy because I never paid attention to any of my other coffee makers to see if they did the same thing. I just got to the bottom of my first mug, There's sludge from the grounds that went through the reusable filter. Back to the paper filters I guess. May be after the machine get's broke in and limed up a bit inside, the water won't go through the grounds as fast and won't overflow. :BangHead::lol::lol:
