At the faucet showroom.  There on their demo.  I was able to experience the voice iq  oh boy... alexa..pause.. tell delta to heat water to 90°and dispense 4 cups
Out come..varied.   You want me to find delis in the area  If she even took the command.  You have to leave the water level on at all times.  
It took 3 minutes minimum to get water to come out.  
Now looking at the base it looks like the might be already attached on this one... there is the same blue black clip thing at the base.  Take this with a grain of salt.  I am not sure. 

Addressing the battery issue people have had on the touch less.  To be fair there is an ac power adapter to plug in under sink and batteries would be just back up.

Beautiful shape.  Not even close on color...shame
