I have used whoZ for over 10 years now, it is always reliable when we need information about any person or place within seconds! It's great that all data can be accessed from one platform instead of having several different applications open at once in order not lose valuable time searching through them (e-mailing each other).
There could sometimes also still appear some errors with names like first/last initials missing while using this service - but nothing really bad as long your search terms include these fields exactly correct anyway so no big deal there either. If someone needs quick access info regarding persons they would never meet before then definitely give their services an try out because even though its free version has limited features compared too paid ones which come along later down the road; i'm sure many people will find value by being able use such software without paying much money upfront since everything comes up quite fast if needed afterwards anyways ;).
