Query: Bad Coffee Maker

This coffee maker was great, the first two or three times we used it. What could be better than having two travel mugs that you can make at the same time? Well, if you look at the design, the spouts come out each side, and they're connected by a bubble, which is lower than the spouts. So of course after a couple times using it, the coffee no longer went into the cups, but instead started dripping to the bubble, and right down in between the two cups. We deal with that by only brewing one cup at a time now.Our problem now? The mugs are plastic lined with Stainless Shells. There is a small notch in the bottom of the plastic, which is glued into the base of the Stainless area. After it's been heated up and cooled down a few times during brewing, the glue melts, and the liners start popping out of the shell. Then when trying to push them back in, the glue breaks and makes the problem worse. I would definitely recommend getting a different coffee maker.
