Cons
Con Very restricted information on their public website
Nothing about pricing, no actual screenshots, no live demo. Even as an actual customer it is unclear what can be customized to your subscription. The product is real and it is good, but for any actual information, you have to personally contact them. This makes it very difficult to compare them with competitors.
