Every review published on Viva Core follows the same process, regardless of category. Here is how we choose, evaluate, and maintain the products we cover.
We prioritize products that are widely available to consumers and relevant to reader questions and search demand within a category. A product doesn't need to be the newest or most expensive to be covered — it needs to be something a reader is actually trying to decide on.
Each category has a defined set of criteria established before any product in that category is reviewed — for example, materials, stated specifications, ease of use, and value relative to comparable options. The same criteria are applied consistently to every product in that category.
Products are evaluated against others in the same category rather than in isolation, so readers can see how an option stacks up against realistic alternatives before making a decision.
Reviews are periodically checked against current product specifications, pricing, and availability. When a meaningful change affects our assessment, the article is revised and the publication date reflects the update, consistent with our Corrections Policy.
Our research draws on manufacturer specifications and documentation, publicly available consumer reviews, and, where relevant, published industry and safety standards. Claims sourced from a manufacturer are identified as such rather than presented as independently verified.
Reviews may include affiliate links. This does not affect how a product is evaluated. See our Editorial Policy for details on how Viva Core is funded.
