Why do you write this untruth? The module has 3 built-in templates with professional design and ready CSS. Any of these templates you can use right after purchase without any knowledge of CSS. 70-80% of our customers use our templates without changes on their sites. Also we started producing additional templates for those who doesn't want or cannot make them themselves.
If you're forced to change design to yours very strictly - yes, you should know CSS, the same is true for any other module. Great feature of our module is that changing design is simple, easy and convenient and requires just basic knowledge of css.
