Our Standards

How we test, how we stay independent, and why you can trust what you read here. This is the standard every review on this site has to clear. If we ever fall short of it, tell us, and we will fix it.

Independence

What our commissions do not buy.

We are reader-supported. When you buy through a link on our site, we may earn a small commission, at no extra cost to you. That is the entire business. And here is the part that matters: the commission has nothing to do with what we recommend.

We routinely pick products that pay us little or nothing, because they are simply the better product, and we would rather tell you the truth than make an extra dollar. When the best choice happens to be the one that earns us the least, that is the one we point you to.

No company pays us to review their product, to score it a certain way, or to place it above another. We do not sell rankings, and we never will. If we ever enter any kind of paid relationship with a brand, we will say so plainly, in the article where it matters.

The reader comes first

No ads. On purpose.

We run no ads. No banners, no pop-ups, no autoplay video, none of it. We could make thousands of dollars more every month by filling this site with advertising, and we deliberately walk away from that money.

The reading experience matters more to us. We spend a huge amount of time on design and clarity because we want this to be a place you actually enjoy using, not another cluttered affiliate site.

โ€œWe lose real money every month by refusing ads. We think a clean, honest experience is worth it.โ€

How we choose & test

We buy it, we test it, we tell you the truth.

We buy what we test

Most of what we test, we buy ourselves, with our own money, the same way you would. We start by finding the products that genuinely matter to a buying decision.

Sent does not mean endorsed

Sometimes a company sends us a product. A free unit buys nothing here. Plenty never get reviewed at all, because once we test them, they do not meet the bar.

We only recommend the best

We never recommend a product the data does not support, or one we would not spend our own money on. When something is not worth it, we say so plainly.

We build our own independent testing methods for each kind of product. The goal is always the same: isolate the variables, measure against the right reference, and find out which product is actually best, not which one markets itself best.
  1. 01Isolate the variable that matters, so the effect we measure is the effect that is real.
  2. 02Use statistical analysis and more than one way of testing, so a single fluke reading never passes for a finding.
  3. 03Publish as much of our method and our raw data as we can, so you can check us rather than just trust us.

A full testing-methodology page, with the exact instruments and models we use, is coming soon.

Every review

What you get on every review.

The things we commit to putting in front of you, every single time.

Weighted scores

Where a clear score helps you decide, we give you one, weighted across the factors that matter for that product.

Full databases

We publish databases with the hard measurements side by side, so you can see how every product stacks up.

Pros and cons

Every review gives you the good and the bad. If a device has real weaknesses, you will read about them.

A plain call

When something is worth it, we say so. When it is not, we say that just as plainly, and we tell you why.

Some products are excellent at one thing and poor at another. A SAD lamp might have a beautiful spectrum and still be useless for travel, so we score when it genuinely helps, and we tell you the trade-offs when it does not.

Who does the reviewing

We become the expert before we test.

We are not physicians, and for a lot of what we cover, there is no credentialed authority to hand you the answer. So we do the work ourselves, and we go deep. Before we test a single device, we spend weeks and often months studying the product, the technology inside it, and the science behind it, until we genuinely understand what actually needs to be measured. Only then do we design a methodology and start testing. Some of these projects run into hundreds of hours. Our continuous pulse-oximeter database alone took four months of near-daily work before it was ready to publish. We would rather take that long and get it right than hand you a fast, shallow review. You can see exactly who we are, and check us for yourself, on our author pages: Brent Baker and Derek Antosiek.

Primary sources

We build on peer-reviewed science wherever it exists, and we cite it so you can follow it to the source.

Corrections

When we get something wrong, we fix it, promptly and openly, noted right on the article. Spot an error? Tell us.

Kept current

We date our articles so you know when a product was tested, and we refresh coverage as new products arrive.

Made by humans

We run every test, do every edit, and take our own photos and videos. AI may help us draft, but the judgment is ours.

You are supporting two families.

This is a small, independent business, not a media company with a hundred staff. When you buy through our links, you are directly supporting two families who pour themselves into this work and who turned down the easy ad money to keep this site clean for you. Thank you for that. It genuinely makes what we do possible.

We read every comment

Tell us what you think.

We are real people, and we would genuinely love to hear from you. If a review helped you, tell us. If you disagree with us, tell us that too. Leave a comment on the article, and we will read it and reply, because we read every single one. For a small team doing all of this by hand, it means more than you know.

The honest bottom line.

We test with our own money, we take no ads, and we recommend the product the data says is best, even when it pays us nothing. That independence is exactly why you can trust everything on the other side of it. For the specifics of how the money works, see our Affiliate Disclosure.
