The Black and Decker 12 cup coffeemaker has a very wide mouth carafe, which is amazing in being able to properly wash it. I was able to put my entire hand inside to clean it.  The thermal carafe seals well and the coffee stayed hot for several hours without the need of the pot being on.  The water reservoir does have an overfill opening so if you are not careful and overfill it will run out the back onto your cabinet.  Just make sure to not add more water than what it will hold.  The shower head type design to brew the coffee seems to do an adequate job of water going over more grounds of coffee at once.  It did take some time to brew an entire pot, but it does have the ability to pause and steal a cup while it is still brewing.  The programmable option is great if you want the coffee ready at a certain time and was easy to use and program.
