The best part about quantum CMS was its ability to create custom modules for my website that I can use as per need without having any technical knowledge of coding or HTML/CSS etc., Also, it has an inbuilt blog module which helps me publish articles easily from within admin panel itself. 1) It's not easy to understand at first but once you get used with its interface then everything becomes very simple2.) There are too many features available out there but some may be confusing3.) Not much customization options4.) Pricing could have been better5.) Support team doesn't work efficiently6.) If they don’t provide support when needed we will loose our customer base7.) No more updates8.) Couldn't find proper documentation9.) When using this software make sure your internet connection speed should be above average10.) Don't forget to check demo version before purchasing11.). Have patience while learning12). Documentation13.
