Google requires you to have an enterprise account or a single Kiosk license to run these in Kiosk mode.The units worked great! Especially as Digital Sign Kiosks. I ran into an issue with getting them into Kiosk mode but that was not fault of the unit. That was me. User error. Thus 5 start still. I just wish I knew this going into it. An outside company said these are what we need. mentioned nothing about the google enterprise account and so on.
