The best part of it I've seen so far has to be that they are really customer oriented! They listen what we want in our projects from start till end - even when things go wrong or something new comes out (like e-signatures!). There's been no hassle at all with their service department since my first contact until now; always professional but also very flexible as well! We're still using them because i would like see how other companies compare afterwards :). But overall everything works great without any problems yet ;-)I don't think there could possibly come anything negative about this system anymore than already stated above :) It might not look super fancy while being used everyday which sometimes can get annoying depending upon your needs/requirementsBut once getting started its worth every penny spent ;) The automation is great. I can set up a project and leave it alone. It will do all the work for me. It is easy to use and it has a lot of features. I haven't found anything I don't like. It is a great tool for the construction industry. I have used it for years and it has never let me down. I have used it for a variety of projects. I have used it for both residential and commercial projects. It is a great tool.
