This Kevo 2nd Generation lock is a definite step up from it's predecessor in terms of build, quality and functionality. While I enjoyed using the 1st Generation Kevo, this lock has a more solid build, a cleaner look and just plain sounds better when it opens and closes. An improvement on an already solid product. I would, however, highly recommend bringing in someone with experience to install the lock as it's not something your typical consumer will easily grasp. It's a small issue but one worth noting. Bravo Kwikset for your continued efforts and here's hoping you'll integrate with Apple's home kit in the near future.
