About stierproducts

stierproducts publishes a single S-to-F board for each of 260 consumer product categories, covering 4,117 ranked products. Every board is assembled the same way, by the same public formula, and every placement on it points at the sources it came from.

We do not test products

We are a review aggregator. We read the outlets that do test products, in volume, and consolidate what they concluded into one board per category so you can see the whole field at a glance instead of reading twenty reviews.

The other half of that is the part most sites leave out, so it goes near the top rather than in the small print. Nobody here unboxes a vacuum cleaner, runs a monitor through a colorimeter, or takes an action camera down a river. We own none of the products we rank and we have hands-on experience of almost none of them.

What we do is read the people who do test them, in repeated independent runs, and let the tiers fall out of how products place across those runs. No tier is ever typed in by hand. How we rank sets out the whole model, including the numbers.

So treat a board here as a well-sourced summary of expert opinion, not as a test report. If you need to know how a specific unit performed on a specific bench, follow our citations to the outlet that actually measured it. That is what they are there for.

Where we are weakest

Coverage is uneven. Some categories are backed by a dozen outlets and some by two, and a board built on thin sourcing is marked as such rather than presented with the same confidence as a well-covered one. Prices and availability change faster than we re-research. And because our input is published reviews, we inherit their blind spots: products that reviewers ignore are underrepresented here too, however good they are.

Who builds it

Noah and Yochanan Liebenberg, as a two-person side project rather than a company. Nobody is paid to place a product. The site is legally operated by Noah, which is stated on terms of service.

Corrections

If a board is wrong, a citation misrepresents what an outlet said, or a link points somewhere it should not, tell us and we will fix it. Email info@stierproducts.com. Corrections to the underlying data are picked up the next time that category is re-researched, and the board's date changes with it.
