  • Rated 5 out of 5 by from Love this coffee maker! I've used this for 2 weeks now and I couldn't be happier with it. It brews a full pot of coffee very quickly and it looks great in my kitchen.

    Rated 1 out of 5 by from Returning Programmable start time does not retain the time. I want to set it and forget it, not have to set it every night.

    Rated 2 out of 5 by from Burns hand when pouring coffee This coffemaker is an utter disappointment. We are returning it as it burns your hand when pouring from the carafe. Steam escapes from an opening by the handle. It's very cheaply made. Should have a $19.99 price point.

    Rated 5 out of 5 by from An excellent cup of coffee! I just unpacked this yesterday, and made my first pot of coffee. It was as good as drip coffee can be (pretty good). Comes with a gold mesh filter and for my first cup, I used that, but as I write this, I am sipping coffee from a standard #4 Melita unbleached filter and I like it even better. A mighty tasty cup made from a well known coffee blend. I like the easy to read water volumn gauge and the controls on the front are subtle. Unlike the maker that preceded it, this coffee maker does not bathe the kitchen in blue light when the lights are out. So I am happy. Sits nicely on my kitchen counter and does not take up too much space.

    Rated 5 out of 5 by from Great find! This coffee maker is fantastic! We purchased it to replace our old Cusinart PerfectTemp 14 cup machine. This new machine brews very hot coffeee quickly ( 7 minutes for a full pot), which was my main reason for getting rid of our old machine. This one is beautiful and takes up less space on our counter. It is easy to move back and forth to fill up the water tank because it is not heavy. It seems to be as good or better quality than our old Cuisinart and costs about half the price! Love it.

  • Does this beep when the brew is complete?

    Asked by: THammerTime
    Hi THammerTime, When the brew cycle is complete, there will be 3 audible beeps and the coffee maker will advance to KEEP WARM function and the TIME SINCE BREW icon will appear on the LCD display. This coffee maker is equipped with a pause and serve feature. The flow valve is located on the bottom of the removable filter basin and is activated when the carafe is removed. This design makes it possible for you to remove the carafe and pour a cup of coffee before the entire carafe is brewed. You must replace carafe within 30 seconds of removing during brewing process.
