Quick and easy. A bit slow for us who are jonesing for the 1st cup of coffee in the morning.  Second down side would be the reservoir could be a bit larger. It does 4 cups before needed a refill. Which, TBH isn't bad. I use the hot water to make iced tea throughout the day so I go through several cups. 
Small size is nice for a limited counter space. The last two Keurigs I have had just stopped working so I went with an old school reliable name brand.
