Being the owner of the world’s 4th largest collection of Mike Schmidt mustache trimmings, I frequently worry about burglars. That’s what makes the Lockitron ($149) so appealing. Just put it over your deadbolt lock and you’ll have the ability to lock and unlock your door from anywhere in the world via your smartphone. That means no need to leave home without keys, no fretting over whether you remembered to lock the door, and no concerns about someone making off with your stash of ‘stache hairs.
