My husband is a chronic coffee drinker. He used to keep a pot of stale coffee warm all day, but has really embraced the k cups. This unit offers him both options, but he hasn't brewed a full pot yet. Thanks to k cups, our counter is a lot cleaner than it was with ground coffee. I also like to use this to brew tea and k cup cocoa - perfect portioning and brewing instead of boiling a whole pot of water. We give it 4 stars because the k cup needles plug easily. We use it so much, that we would love to have a water line hookup, but that seems silly.
Update - not a fault with this product, but wish K-cup unit needles didn't plug so often. We've had to be much more diligent in removing the k cup holder and rinsing it out or else the 3 serving size lights will blink to let us know the unit is plugged. A paper clip threaded through both the top and k cup holder needles and then a couple cycles to rinse out the clogged grounds has fixed the issue, but it is a pain. We haven't found anything in the manual or Cuisinart website regarding this, but the internet abounds with help.
