I've had this almost a year now. It's absolute junk. I've calibrated it several times but it really has a mind of it's own. It will lock/unlock when you go through, regardless of if your phone is on/near you. The molding around the door is basically trash now because the deadbolt opens on its own while my hands are full and then slams into the molding. This lock goes to the garage or I would have replaced it a LONG time ago. Now I'm just hoping the battery dies soon.
