I love the fact that I no longer need to keep keys on me to lock and unlock my door. There is a slight delay, but I can unlock the door with full hands now. The back of the product on the inside is a bit big, but you get used to that pretty quickly. The locking/unlocking is also a little loud, but again, easy to get used to. And giving out keys and using them through the app is easy - so even my mother can now use this lock at my house.
