Ultraloq Bolt Fingerprint for $200: I have now tested three different Ultraloq smart locks over a year and a half, and while I think the company offers excellent hardware for the money, there are just a few too many software quirks that put these locks a rung below our top picks. Yale Assure Lock 2 Touch for $300: I've been testing this lock for a few weeks in tandem with ADT's security system and Google Home. Instead of using the Yale app, I primarily control this app with the ADT+ app, but there are versions of this lock that don't use or require ADT's service.
