The ease of use once you've read through all the documentation available. It's also very easy to add new sites/projects if needed. We're able to complete inspections in under 2 days now that we have this system set up without having a bunch of inspectors out there doing it manually. There isn't much for us to dislike about the software at this time.
I would say one thing - when first installing, your sales rep will be really helpful setting everything up correctly. This can save time laterβ¦
