To help make a quick judgment on a compound or brand I am adding a star rating to the review section on the products. The ideas is to get a quick overview of the essential points of the product. I created 5 categories for this task and each is rated.

The first is how well it works for its intend use and fall under "works". More stars under works means it is good. The second is side effects and here more stars ,means MORE side effects or a side effect rating.
Third comes availability, more stars for better availability.
Fourth is cost, good value means more stars.
Overall rating based on experience and feedback, more stars means good.
Hope this helps.
