I like that this software can run with an internet connection so we don't have to worry about our computer crashing while running multiple screens of content for many different locations at once! It's very easy using creating margin as well when adding new users which makes setting up projects much easier than other programs out there!! Nothing really but if something does happen they are quick enoughtat getting back online/fixed whatever issue was created by their system being down haha :) We just use them mostly because everyone knows how good these guys work (and trust me - my husband has used every single one) They will help set anything from 1 screen all around campus through 10+ throughout town-side buildings etcetera.
