The ease of switching between the carafe and kpods 
Is pretty easy what I don’t like about it is the water tank for using the carafe is located behind the coffee maker you constantly have to keep moving the coffee maker forward to fill the tank. The water tank for the kpod is on the side which is okay. 
As far as the frother for the milk it would be nice if it was a  little shorter to accommodate your cup.
Check the dimensions of the coffee maker to make sure it will fit under a your kitchen cabinet some people have had problems with this
