This is my 2nd Keurig K15. I purchased this with earned points plus cash.  November 15. 2016, and received it a couple days later. 
 This one doesn’t  get as “HOT” as my first one.  I have to microwave my coffee after I add my cream. I didn’t with my first one.  I am disappointed with this machine.
I wonder if the heating element might be defeated in this unit  .
