This article claims that Miracle Sheets use NASA-inspired cooling technology and have silver-infused antimicrobial properties that are able to reverse skin and allergy issues. These are intriguing claims, but they lack any elaboration on how it works specifically, and provide no sources to support the claims.
The article is written through an individual's experience, and yet makes claims that generalize to everyone, which is misleading. It is also clear that this article is trying to sell you the product based on the many links and positive reviews shown throughout. It is obviously a biased source with the goal of selling the readers a product, rather than provide an unbiased review of it.
