Been using this lock for several months now and am incredibly happy with it. The combination bluetooth and wifi has been a huge improvement that's made connectivity issues a thing of the past. I initially started using the lock during the beta test process and can say that the software improvements August has been making are phenomenal. If you are on the fence between this and a previous version, absolutely get this one. The homekit setup, because of the dual connectivity options, was incredibly easy and straight forward.
