I received the 980 Deadbolt with Smart Key from the Try It Community.  It keeps my door closed nice and tight.  No more worrying about someone cutting off the bolt in the door.  The smart key helps me not worry about anyone picking the lock.  Since I've installed it, I've been able to leave my house and know it's secure from pesky people, trying to steal from me now that my husband has passed on.  It was easy to install, I was able to do it myself.
