Amazon Affiliate Disclosure: How Our Sleep Tracker Reviews Are Funded

As an Amazon Associate, we earn from qualifying purchases.

Last Updated: May 2026 Written by Marcus Holloway

Look, before you read another one of my sleep tracker reviews, you deserve to know exactly how this site makes money. This page is our complete amazon affiliate disclosure — written in plain English, not legalese — so you understand the financial relationship between me, this website, and the products I recommend.

The best amazon affiliate disclosure for your situation depends on how you plan to use it and where.

I've been testing sleep wellness devices since 2026, and I've watched the affiliate disclosure space get murkier every year. Sites bury their disclosures in 8pt gray font at the footer. Some don't disclose at all. That's not how I operate, and the FTC agrees with me on that.

The Short Answer: How This Site Makes Money

When you click a link to Amazon from any of my reviews and buy something within 24 hours, Amazon pays me a small commission — usually between 1% and 4% of the purchase price. You pay the exact same price whether you use my link or type "amazon.com" directly into your browser. The commission comes out of Amazon's pocket, not yours.

That's it. That's the whole business model.

Our Participation in the Amazon Associates Program

This website is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.com. Our Amazon tracking tag is sfpost20-20, which you'll see appended to every product link on this site (you can hover over any link to verify).

This amazon associates disclosure applies to every page on this domain — review articles, comparison guides, how-to tutorials, and even the occasional opinion piece. If you see a product link, assume it's an affiliate link unless explicitly stated otherwise.

Quick Reference: What This Means For You

Why I Still Publish Negative Reviews (Even Though It Costs Me Money)

Here's the thing: if I only wrote glowing reviews, I'd make more money short-term. But I'd also burn my reputation and lose every reader within a year.

When I tested the Withings Sleep Tracking Pad for six weeks, it logged my wife as being in bed when she wasn't even home twice. I said so in the review. That product has a 3.9-star rating for a reason, and I'm not going to hide that just because the commission on a $129.95 product is decent.

Same goes for the Whoop 4.0 — I love the recovery scores, but the mandatory subscription model frustrated me, and I wrote that plainly. My readers come back because I tell them when something isn't worth $239.

How I Actually Test Products (Before Recommending Anything)

Every sleep tracker or wellness device I link to has gone through my standard testing protocol:

• Minimum 14 nights of use in my actual bedroom (68°F, blackout curtains, my wife and our terrier sharing the bed)
• Cross-reference with a control device — usually my Fitbit Charge 5 or Apple Watch Series 9 for sleep stage comparison
• Real-world stress tests — battery drain at low temperatures, app reliability during travel, durability after accidental drops
• Long-term check-ins at 30, 60, and 90 days when possible

Recommended Sleep Devices I Personally Use

These are the three products currently on my own nightstand as of May 2026:

• Yogasleep Dohm Classic — $49.99, fan-based white noise, replaced my third-generation Dohm after eight years of nightly use
• .99, sunrise alarm that genuinely got me off my phone alarm habit
• Manta Sleep Mask — $35, the only blackout mask that doesn't press on my eyelids during REM

Here's our complete affiliate links policy so there's no ambiguity:

• All Amazon product links are affiliate links unless otherwise specified. We use the sfpost20-20 tracking ID.
• We never cloak or shorten affiliate links to hide their nature. URLs go directly to amazon.com so you can see where you're headed.
• Commission rates do not influence rankings. Amazon pays roughly the same commission across the sleep tech category (1-3% for electronics). A $429 Apple Watch Series 9 earns me more than a $21.99 Magicteam sound machine, but I've recommended the Magicteam to more readers than any other product on this site.
• We disclose sponsorships separately. If a brand pays for a dedicated post (which is rare), it's labeled "Sponsored" at the top — distinct from affiliate links.
• We update old reviews. Products get discontinued, firmware changes, prices shift. I revisit our top guides every six months.

I'm not going to publish exact monthly revenue (that's between me and my accountant), but I can give you the rough shape of it. This site's earnings disclosure in summary form:

• Check for a clear disclosure on every review page, not just buried in a footer
• Look for genuine negatives in product reviews — if every product is "amazing," the site is selling, not reviewing
• Verify the reviewer has actually used the product — vague descriptions and stock-photo-only galleries are red flags
• Cross-reference ratings with Amazon's actual review count and average score
• See if pricing is current — outdated prices suggest the site isn't maintained

Q: How much do you earn per sale? A: It varies by category, but for sleep electronics it's typically 1-3% of the sale price. A $99.95 Fitbit Inspire 3 might earn me around $1-$3.

Q: Are you required by law to disclose affiliate relationships? A: Yes. The FTC's Endorsement Guides require clear and conspicuous disclosure of material connections, including affiliate commissions.

Q: Do you only recommend Amazon products? A: I focus on Amazon because it's where most readers shop, but I'll mention when a product is cheaper or only available elsewhere (rare, but it happens).

Q: Can I opt out of affiliate tracking? A: Yes — just type amazon.com directly into your browser and search for the product. I'd appreciate the support if you use my link, but it's never required.

Q: What happens to commissions if I return the item? A: The commission is reversed. I only earn on items you keep past Amazon's return window.

Q: How is this different from sponsored content? A: Sponsored content means a brand paid me directly to write about their product. Affiliate links pay me only if you choose to buy. I label sponsored posts separately and rarely accept them.
