We previously owned a Keurig 2.0 brewer which performed flawlessly for more than 8 years! Lately, the brew temperature started to decrease. After 8 years service, the heater element no doubt was "worn" out. As a replacement ,we purchased the K-Supreme SMART.  What an upgrade. It allows to adjust all aspects of the brew and recognizes the K-cup product you are using.  The test of my brews are all outstanding and hot.  I need to try the ice coffee brew.  It's incredible what technology can do to improve a cup of coffee!  Thanks Kuerig!
