In theory, this is an awesome product. Unfortunately about 80% of the time when I go to use it, the application on the iPhone requires you to log in. Doesn't matter if it's been 5 minutes since I last used the lock, or if it's been 5 days. SO ANNOYING! How have they not figured this out yet?! While it's very convenient not to have to use my keys, it's less convenient to have to type in my password every time I use the app. Come on Kwikset, you're better than this!
