This is a valid concern for the whole review space. That's why most people don't trust a single source and look at multiple opinions (4-7 websites on average). One single source will never provide "just enough" research for a product you plan to spend a lot of money on and use for a long time. There is often at least one deal-breaking issue that you will find after reading through different sources.

We belive that a product research engine that provides honest and transparent recommendations from trusted sources is still a massive improvement over the current process.

We're not immune to the "garbage in - garbage out" problem, but we do our best to keep track of and remove sources caught getting paid to write fake reviews. Some categories are more prone to astroturfing than others, and we account for that by restricting the sources. Actively curating the sources is part of our daily work.
