I have two of these (black and silver) for my front and back doors, both with keypads. Each were a breeze to install. The instructions are extremely simple, well-articulated, and the video tutorials are an added bonus. I enjoy the modern, sleek design that's non-traditional compared to other locks. 

The app is well-designed and intuitive. Response time of lock/unlock is very good. The amount of control you have via the app is nice.
