This lock installed easily and looks very modern.  I would say the app is moderately easy to use but there are a lot of options on this lock that was a bit overwhelming at first.  I like the option of not always needing a key to get in my house if I do not have a key handy.  I do not really use the app for anything very often and likely would not ever really need to access it remotely.  I am not really utilizing the WI-fi portion to its full potential up to this point.  It was also not too much of a pain to re-key the actual deadbolt portion of this lock to match my existing house key without a locksmith using the "Smartkey" functionality.
