I give this 4 stars only because there is one thing they could do to make this machine perfect - add a grind and brew feature.  Otherwise I would give it 5 stars.  Other than that, I am very much enjoying it.  The water capacity of the single serve is quite adequate and I love that it makes both Keurig and Nespresso pods.  I replaced a Cuisinart SSGB-1 which has grind and brew pot and Keurig single serve.  I had a Nespresso machine next to that.  The grind and brew was quite a mess to clean every time and the water capacity of the single serve was small.  
My new machine lets you choose the size of Keurig and the size of Nespresso.  It also has a milk frother attached which can be used for hot water for making tea.
If Cuisinart ever can figure out how to add a grinder to this machine it will be perfect and I'll be first in line to buy.  If you're looking for testers, Cuisinart, count me in!
