I love this machine. Great ability to connect to our internet despite wondering if it would. Alexa makes it very simple to start a drink in the morning.  The Signature brew is off when it comes to teas.  I have found that brewing them at a higher temp and strength works best for me. It removes the bitterness for me.
 The app does not list very many recipes. I hope they will bring out more soon. I hope they will include more complex recipes. Brewing coffee, frothing and then adding to a cup just is so boring. There must be other recipes. 
 The Smart Delivery needs to be easier to change out. I want to be able to try different K cups and swapping them out is hard to do on the site.   Over all, I am happy with this machine and what it can do. It has made coffee and tea fun to work with and not just drink as is!
