No problems with over-fill, looks nice in the kitchen and the coffee has a fresh taste and smells great.  It is also easy to clean, which is very important to me. I have only one suggestion for the manufacturer and that would be to extend the length of the electrical cord.  Most coffee makers are placed below overhead cabinets, which can cause damage to the under side of the cabinets, but if the cord is a little longer, the coffee maker could be moved forward so the steam doesn't cause problems.
