The ease of use was one for me! I had not used an install ssl solution in years but this is so easy that almost anyone can do them now without any problems or issues at all - even my IT guys who don't like anything technical found they could figure out how things work quickly with just some basic training (which i provide). They also have such great customer support which saves you time solving their questions as well when needed. It's been over 2 months using autoinstall sssl server software yet we still get emails asking about our setup every week by new customers trying us! We love being able to focus solely getting sales going again instead worrying about what certificate provider will be best etc..
