I took a chance on this as I was intrigued by technology and functionality,. Never got to experience it because my gate lock, as 100s of others, wasn't  specifically designed to allow for installation of this. If you have keys on both sides, vertical screws, lever separate from key entry, deadbolt location questions, etc... do not buy as this wont fit. The worse part, and reason I am here, they do not try to solve this with you and make return process a nightmare, including having to spend a significant amount of $$  just for the privilege of having to ship this back. Unacceptable.
