As a non-profit, our only concern is helping you buy products that work and are safe based on your needs. This is why we focus on rigorously testing products for specific usages and making sure they will work for those. This way we are confident that if we say it will work and it's safe to use it will be the case. We believe that the most important questions to answer to help you buy good online products are: will it work? and is it safe to use? Those vital questions deserve a clear yes or no answer which is why we choose to focus on recommendations and don't provide ratings. A recommended product will be safe to use and will work for your use-case. No ambiguity.
Let's take tea as a concrete example of why clear recommendation are the best way to provide valuable advice:
If we recommend a specific tea it is because we have rigorously tested that it is free of toxic content and really contains only tea so you will be confident drinking it will not poison you.
We don't make subjective judgments on how it tastes or if it is worth the price asked. That is up to you!
