I like everything about this system! It's easy for people who are not tech savvy or have never used it before because they can figure out how things work very quickly once their learn what buttons do different tasks etcetera (like any other computer program). There really isn't anything as far as complaints go; just make sure when signing in/up if there aren’t certain options available yet but be patient with them adding more features over time because sometimes these programs take awhile - especially ones such as kent house which has been around forever!! If anyone wants something simple where guests need little assistance then use KENT HOUSE. !
