The customer service is amazing! I have never had any issues with them or their products at all. They are always willing to help and respond quickly, if not immediately. And they make great software too. It's easy for me to use because it works well in Excel as well as Power BI. I like that you can do everything in one place instead of having to go back and forth between two applications. If you want something robust and reliable then this product is definitely worth your time and money. We were looking for an advanced tool that could handle complex data sets and provide us with some insight into our business processes. This allowed us to create predictive models we weren't able to build before using Statgraphics.
