Our standards

Honest studies need honest rules.

What you get, what we ask, and the rules every study follows, written down before anyone signs up.

The one rule

We pay for the work. Never for the verdict.

Love it, hate it, or “it did nothing”: you get exactly the same. Tell us what really happened.

Here's the deal. Written down first.

Every study spells this out before you sign up. Here's the mouth tape study.

What you get

The tape, yours to keepFree. You cover $6.95 shipping, and that's stated up front.
Your own answerYour nights with it and without it, side by side, in plain words.
First pickTesters hear about new studies before anyone else.

What we ask

Two minutes to sign upA few questions, including a safety check.
About a minute a morningFor 6 nights, from the link in your email.
A few last questionsAbout two minutes at the end.
The truthIncluding “it did nothing.” That's a real answer, and a useful one.

We pay for the work. Never for the verdict.

01
Nothing you say changes what you get.
What you get is set before you start. A great review, a bad one, or “it did nothing” all count the same.
02
Safety comes before shipping.
Every study starts with a safety check. If it isn’t a safe fit, it says so before you pay anything.
03
One tap stops everything.
“Something’s wrong?” is on every study page and email. It pauses your study, and a person writes back the same day.
04
Ownership is on the label.
When a study tests a product from an Evident brand, the study page says so, and so does the consent.
05
Results are totals, never people.
A study’s public results open only once 10 or more testers finish. No names, and quotes only from testers who said yes.
06
A person runs every study.
Your answers are added up, not rewritten. No AI writes your results, and payment never depends on what you say.

No surprises. Just your answer.
