Black Friday 2026 · Free Chrome extension

Is your Black Friday list actually worth it?

Every deal comes with a claim. Clinically proven. Dermatologist recommended. Best in class. Paste what you're planning to buy, and before the sale starts we tell you two things.

1
Is the claim true?

We check every claim against real sources and show you what holds up, with the links.

2
Is there a better buy?

We find options that do the same job for less, or do it better for the same price.

Early access: the first 20 sign-ups get unlimited checks through December 31, so you're covered for Black Friday, Cyber Monday and the holidays.

One email: your verdicts and the install link. No account, nothing else, ever. Privacy

Worth it

Athletic Greens AG1

Two claims supported by ingredient trials, one mixed, two unsupported. Three cheaper greens powders named.

  • Supports immune health
  • Improves stress response
  • Complete daily vitamins

Better options

Amazing Grass Green Superfood

Lower price, lower quality

A similar greens blend for a fraction of the price, with fewer added nutrients.

Skip it

Anker Prime Power Bank 20000mAh

The maker has documented fire-hazard recalls on its power banks, and the capacity and output claims have no independent test behind them.

  • Charges phones and laptops on the go
  • 20,000 mAh capacity
  • 200 W output

Better options

Baseus 140W Power Bank

Lower price, lower quality

Less output, but no recall history and costs less.

Depends

CeraVe Moisturizing Cream

Well-studied ingredients, but the claims rest on ingredient evidence rather than tests of this cream. Two cheaper alternatives.

  • Restores the skin barrier
  • Hydrates with hyaluronic acid
  • Smooths texture with niacinamide

Better options

Vanicream Moisturizing Cream

Same quality, lower price

A similar barrier-repair cream, fragrance-free, for less.

How we rate

Worth it

At least one of the product's claims is backed by an independent source, and nothing is documented against it.

Skip it

We found a recall or safety action, a claim the evidence contradicts, or a clearly better value for the same thing.

Depends

The evidence is thin or mixed, so the answer rests on what you need it for. We say so rather than guess.

Sources we use: medical literature (PubMed), U.S. recall records (CPSC and FDA), and the product's own listed ingredients or specs. The brand's own site never counts as evidence. Every cited page is fetched and checked before it appears.

How it works

  1. 1

    Open a product page

    Any store on the web. A small badge appears in the corner when the page sells something. Nothing to turn on.

  2. 2

    Tap "Check this product"

    We read the brand, name, price and ingredient list, research the product, and verify every citation by fetching it.

  3. 3

    Read the verdict

    Worth it, skip it, or depends, and why. Each claim with its evidence and source. Better options that say what differs: same quality for a lower price, or better quality for the same price.

The panel on a real store page: the verdict, then three better options and what each does differently.

Questions people ask

What happens when I submit my list?

We check each product the same way the extension does and email you the verdicts, along with the install link. One email. If you install the extension first, the products on your list open instantly.

Which stores does it work on?

Any https store: Amazon, Walmart, Target, Sephora, Ulta, Best Buy, and every brand's own site. The badge appears when the page sells a product.

Does it cost anything?

No. Your first 5 checks need no account, a free account gives you 5 more, and a product anyone has already checked is free to open as many times as you like. The first 20 sign-ups get unlimited checks through December 31: create your account in the extension with the same email and it applies on its own.

What does it read from the page?

The product's brand, name, price, ingredient or spec list, and the site's domain. Not the full page address, not the page's HTML, not your browsing history, not other sites' cookies. On a page that isn't selling something it sends nothing.

Where do the verdicts come from?

Published evidence, found and read for each product: studies on PubMed for ingredients, recall records at the CPSC and FDA for the maker, and the product's own listed ingredients or specs. A model reads those pages and writes the verdict; every cited page is then fetched and checked, and anything dead or off-topic is dropped. The rules for the three ratings are in "How we rate" above.

What about the affiliate links?

As an Amazon Associate we earn from qualifying purchases. Links that earn us something are marked in words beside them. Commission never changes what is recommended or the order.
