[This review was collected as part of a promotion.] This lock has been wonderful to use. You can create separate codes for different people so you know who’s entering/exiting your home and you can end their access easily or add someone new. No more worries about getting keys made and getting keys back from people. Another great feature is if someone forgets to lock the door or you have your hands full you can lock/unlock the door from the app. No more worries about getting locked out or having to carry around keys. The lock works with Google Home and is connected by either Wi-Fi or Bluetooth.
