Before You Scroll Past This Page...
Let's be real for a second. Nobody wakes up excited to read a Terms of Service page. Not you. Not me. Not even the lawyers who write them.
But here's why this one matters: we test physical products that touch your body and influence how you sleep — wearables, smart rings, white noise machines, sunrise alarms, and bedside sensors. That's not the same as recommending a stapler. So before you click an affiliate link or trust a review verdict, you deserve to know exactly what this site is, what it isn't, and where our responsibility starts and stops.
Grab a coffee. This will take five minutes. I promise it's written like a human, not a contract.
The 60-Second Summary
> TL;DR — If you only read one section, read this one.
| # | The Promise |
|---|---|
| 1 | We review sleep wellness products based on real, hands-on testing — not press releases. |
| 2 | We earn commissions through Amazon Associates when you buy through our links. |
| 3 | Our content is informational — never a substitute for medical advice. |
| 4 | You are responsible for your purchase decisions and how you use any product. |
| 5 | We update reviews regularly, but Amazon specs and prices shift faster than we can edit. |
1. Acceptance of These Terms
By browsing this site, subscribing to our newsletter, or clicking an outbound affiliate link, you agree to the terms below. If you don't agree, please close the tab — that's the cleanest way to opt out. These terms apply to every page on this site, including product roundups, how-to guides, and comparison tables.
We reserve the right to update this agreement. When we do, the "Last Updated" date at the top changes. I personally review this page every quarter — usually when I'm refreshing our sleep tracker rankings with new test data.
> Pro Tip: Bookmark this page. If you ever wonder "wait, did they change something?" — the date stamp is your answer.
2. About Our Content and Testing
Every product we recommend has been tested in my home sleep lab — a converted spare bedroom with:
- Controlled lighting (blackout curtains + adjustable bias lighting)
- A Hobo MX1101 temperature/humidity logger running continuously
- A calibrated SPL meter to verify white noise output in decibels
- An Oura Ring Gen 3 worn as my reference baseline
Watch How We Actually Test Sleep Trackers
> The honest truth: My body, my mattress, and my bedroom aren't yours. A sleep tracker that scored my deep sleep accurately against an Oura reference may behave differently on your wrist. Treat our reviews as informed starting points, not prescriptions.
Products We Cite Repeatedly Across This Site
These three earn their mentions because they've survived long-term testing — not because anyone paid for placement:
- Fitbit Charge 5 — our most-cited mid-range tracker. Check Price on Amazon
- . Check Price on Amazon
- Yogasleep Dohm Classic — the mechanical white noise machine that's lived on my nightstand for three years and counting. Check Price on Amazon
3. Affiliate Disclosure & Commercial Relationships
This site participates in the Amazon Services LLC Associates Program*. When you click a link marked "Check Price on Amazon" and complete a purchase, we earn a small commission — typically 1% to 4% of the sale price.
> Your price never changes. Not by a penny.
I want to be specific about what this does and does not influence:
What it does NOT do:
- It does not affect our rankings. The Withings Sleep Pad earned a middling score because it had connectivity dropouts in week two of testing — not because of its commission rate.
- It does not unlock "sponsored" verdicts. Brands cannot pay for a higher position.
- It does not influence what we criticize. If a $400 device underperforms a $90 one, we say so.
- It means we tend to review products available on Amazon, since that's where most readers actually buy.
- It occasionally means we receive review units from manufacturers — which we always disclose at the top of the relevant review.
- It keeps the lights on, the test logger calibrated, and these reviews free for you to read.
Understanding Affiliate Disclosures (Why They Matter)
