I was surprised at how easy it was to install and get working. I have installed several faucets over the years and looking inside the packaging for this faucet I was initially intimidated. About an hour later, everything was working. The Voice IQ has been fun as well as helpful. Just ask Alexa to tell Delta to give me 1 cup of water. To my surprise, it was extremely accurate. The Touch feature has been something we have found we can’t live  without now that we have it. The only head scratcher for me was why have the battery pack with 6 AAA batteries and the hardwired plug in. It seems power from the hardwire would have been enough to power both modules. Maybe there’s a technical reason, but either way, everything worked flawlessly after installation.
