I LOVE this lock! It is so convenient as a busy mom. I can hop on the app and see if the door is open or closed, locked or unlocked, and control it from my app!  If my hands are full, the door lock is the least of my worries because I can now control it before or after getting in/out of the car with no problem!  That makes things sooo easy! 
I installed it myself and while one of the steps was a little confusing, I got it working and installed in no time. The installation instructions were on my phone which was also convenient. 
It looks great and the locking mechanism is super smooth. Highly recommend and will definitely purchase another for my other door!
