[This review was collected as part of a promotion.] The home system I never knew I needed! I am currently redoing my mudroom and a new smart lock was a perfect addition! Very similar to the key less locks used at Air BnB’s, and easy to install. I love the feature of having an app on your phone to be able to unlock your door. Hands full of groceries? Unlock your door from your car! My only concern would be that the battery life only lasts for a certain amount of time. I believe a little over a year so after a year, you would have to change the battery I believe.
