I have been using it for over 1yr+. Prior to purchase Kevo, I did a lot of research how other keyless works. Many others were inconsistent, some uses GPS where touch isn't required at all, the problem I found others was I am living in an apartment building where GPS could be showing me I am at another building or worst another location.
The other reason I choose Kevo was externally it looks like a normal key lock but can open by touch sensor. In year 2014 when I first got it, only my Samsung Note 4 were able to open the door, now I can use my Huawei Watch (Android Wear) to open it too. Thanks to Kwikset Kevo and thanks to David Krauser for actively improving.
