but if you care about getting a really good X, they're not a great source. most of their buying guides have a lot less detail than Wirecutter's, and of course pale in comparison to dedicated review sites for popular niches.

They rate products in a bunch of categories using a table and a circle which would be various levels of full color depending on how a product rated. which meant sometimes you wouldn't just go to the highest rated if one part of the product scored lower in a category. Its an interesting data visualization method. Plus the table usually has specs too.

Unfortunately, they also require summarization, so they're only as good as the individual quality projections into discrete levels. Powerful when used correctly. Useless when incorrectly, or your audience isn't visually-oriented.
