What is everyone’s luck with “Automated Bean to Cup”?

Lately a lot of new super automatic espresso machines are coming out with software to take the guess work out of manual grind adjustment, coffee to water ratios, temperatures, extraction time, etc.

Recently released DeLonghi PrimaDonna Aromatic, Ninja AutoBarista Pro, and KitchenAid KF4 are some examples to incorporate this technology.

Has anyone purchased any of these new machines that promise to automatically tune your espresso shots to perfection? Which one did you get? Do you like this automatic feature? Does it work well or do you still find yourself fine tuning your own brews?
