We love this product so far, and it has been a great addition to our home security and is on our front door. The lock was very easy to install and the app is user friendly.  The packaging and the user guide is simple but clear to understand.  Once the existing lock has been removed, the process to install the new lock is straightforward and relatively easy.  Connecting the lock to my wifi was also simple through the app.  In addition, I set up the supplied cards for using the lock easily along with the app to lock/unlock the door.  The color and finish fit our home perfectly.  The touch feature on the lock was a little glitchy, it didn’t always work when trying to unlock with the touch but after a little practice it works well. Overall a very good product for our home.
