Query: Melitta should be embarrassed

Melitta should be embarrassed that such a flawed product has not been recalled and is actually still available. Like many of the other reviewers, I find it impossible to make two cups of coffee. Either one cup overfills or the coffee drips down the middle between the two cups and runs all over the counter. I haven't had the "exploding mug" experience, but find them so inferior to other travel mugs, I just don't use them. It's surprising to me that the overall rating is as high as three stars.
