The machine is very slow to detect K cup brand and get ready to brew a cup. I also don't like that if it selects signature blend as it does for most of my flavored coffees, I cannot change a single thing such as making it hotter without selecting every setting and I have no idea what it is has selected as best options! I have found that when I select 10 oz cup, the coffee tastes bitter but if I select 8 oz it tastes fine - except for not being hot enough. I never had this issue with my previous Keuring machines. I think this "Smart" is really trying to be too smart and doesn't make a good cup of coffee
