As long as your door frame isn’t wood its not a bad idea, and a pretty proven tech. If the frame is wood or shallow aluminum like having a window next to your door, as we did at our last house, it can be a challenge to fit.
I actually really don't like smartlock deadbolts, because it takes more power to physically move the deadbolt so the battery life is worse. I want it to be hardwired to mains power. (with battery backup and physical key secondary backup of course)
