    The best support I have encountered in 40 years in the business. An excel spreadsheet in the hands of Mohamad is akin to a violin being played by Jascha Heifetz!

    I read all the articles that I could find by Mohamad on principal components analysis. They are top-notch quality and easy to understand. As a bonus, they use interesting data. Although I had already used PCA in my research and I know the linear algebra behind, I found then illuminating. Finally, if I have to explain PCA to non newbies, I would use them as a guide.

    The product contains numerous easy-to-use modules and the interface with Excel is a big advantage, especially the ability to toggle back-and-forth. Tech support is quick to respond and staffed with knowledgeable, friendly, courteous, and patient individuals. So far, the best interaction I've had.
