I used it and it didn't find any deaths in my house, which I figured, but it did give me a list of everyone who ever lived at my house... So if people came knocking at my house for someone I would know the names of people who use to live there! For $12 to do a history check on anyone registered at my house, not just the owners was worth it to me. But that's just me, I work with computers and such and I know they cant have all the information, hell most cities don't have digital records even today... but its only $12 to give it a try!!
