Do not buy this K15 if you like hot coffee. Comes out Luke warm, have to put in microwave to get hot. Also, you don't get the full flavor of your coffee as water not hot enough. I called KeUrig, was told not to use ceramic cup as it made the coffees
 Cool. After some discussion on this, They  were very nice and replaced it with another one but same problem. They paid for return shipping of the original one, 
 So they are very accommodating. I saw reviews on K55 and seems like water is 
hotter. I can't afford to,pay for a K55 after paying for this one.  Very DISSAPPOINTED as I was looking forward to a KeUrig product.
