Love that it can do whole pots, half, hot, cold, K-Cups, etc.  The hot water feature is a super nice extra.  It dispenses from a different spot so no coffee flavor.
The issue we have is when using the K-cups if we don't have a wide, wide, wide cup the coffee goes everywhere.  I mean, that's not super convenient.  In fact, it kinda sucks.  I've contacted Ninja so hopefully it will be addressed.
