They have no Google provided support, if you drop the phone and break it your only option (if you didn't buy the third-party warranty upsell) is to take it to a repair shop. I called the ones near me, none had seen or touched the device before.
Don't spend $800 on a phone that you can't send back to the manufacturer to repair.
Edit: I originally said "they have no warranty" and people seem to have understood that as "they don't provide free repairs" -- what I'm trying to say is that this phone is supposedly a competitor to Apple, but if you break it you can't walk to the Apple Store and ask them how much it'd be for a repair. You can't send it in the mail to them either. You have to go to an authorized third-party repair shop. That does not sound like first-class flagship $800 product support to me.
