Becoming a product tester: how genuine product tests work and how to spot subscription traps

Free products do exist. "Free" is still rare, because someone always pays, and often it's you: with time, with data, or with a magazine subscription you never wanted.

The short answer

"Product tester" isn't a profession but a catch-all for four different things: test products in exchange for an honest review, paid studies involving products, mystery shopping, and checking apps or software. Cash is the exception, selection is often a lottery, and there's no guarantee you'll receive anything. Legitimate programmes ask nothing of you but time and honest answers. Anyone who first steers you towards a subscription, an unpriced co-payment or a deposit isn't one.

Four routes, four very different deals

More on the last two routes is in the guide Earning money with app tests.

How a genuine product test works

1. Create a profile. You state age, household, interests and shopping habits. That's the basis for selection, so be honest: false answers show up at the latest in your review.
2. Application survey. You apply to each campaign with a few questions. At Konsumgöttinnen, per its FAQ, profile and application survey decide, and with equally suitable applications a lottery does too. The campaigns visible on 16 Oct 2026 had 180 to 1,000 places, and the provider says its community has over 330,000 members.
3. Product and deadline. If you're selected, the product is sent to you, you use it yourself and write a review from your own experience.
4. Disclosure. If you show the product on social media, the terms of participation require you to state clearly that you got it free or discounted in a product test.
5. Keep it or send it back? The Konsumgöttinnen FAQ says you can "usually" keep test products. The terms of participation are stricter: the product initially remains the property of the campaign partner and in principle has to go back unless you're told you may keep it. Read that before accepting a campaign.

What to check before you sign up

• An operator with an address. Konsumgöttinnen names Connected GmbH in Frankfurt with a commercial register number. A portal without a checkable operator, you skip.
• What do you get, and what does it cost? Legitimate programmes state any co-payment upfront. At Konsumgöttinnen it's at most 50% of the recommended retail price on very high-value products, and you can return a product you don't like.
• No compulsory subscription. If you can only complete registration with a "trial subscription" or a "free reading sample", stop. That's the pattern in the consumer advice warnings.
• Resale rules. Konsumgöttinnen strictly prohibits reselling test products, per its FAQ. Anyone who resells test goods breaks the provider's rules.
• Independent voices. Check what consumer advice services and review sites say. Testwatch called Konsumgöttinnen's tests disguised product advertising in 2020. That's an assessment, not proof, but a reminder that a test can also be advertising.

Warning sign: the subscription trap with a "product tester" label

Consumer advice centres have been warning about this for years. Registering as a product tester comes with a free magazine trial subscription that is offered or even compulsory, the need to cancel in time isn't made clear, and an invoice follows. The Bavarian consumer advice centre warned about this exact scheme on 9 Dec 2024. According to their warning of 17 Mar 2026, the 16 German consumer advice centres logged more than 21,000 complaints in 2024 and 2025 about a service that collects payments for such magazine subscriptions; among the cases described is one where a data request for product tests ended in a 13-month subscription. In August 2026, the Hanover regional court barred a portal, in a default judgment, from advertising "product tester" registration without disclosing the compulsory paid subscription attached to it (Wettbewerbszentrale, 15 Sep 2026).

This is not legal advice. When an invoice arrives, consumer advice recommends reacting at once: dispute that a contract was concluded if you didn't conclude one, and revoke or cancel at the same time as a precaution. The Brandenburg consumer advice centre gives 14 days from receipt of the first goods for revocation as a rule; without a correct notice the period can run longer.

Realistic expectations

Don't count on income. Per its FAQ, Konsumgöttinnen pays no cash, only goods and bonus points for prize draws. How often members are actually selected isn't documented; the reports are individual voices and forums, some from 2014. With studies and mystery shopping, providers pay an amount per assignment, but invitations and assignments aren't guaranteed. If you treat it as a hobby with an occasional bonus, you'll rarely be disappointed. If you plan on an income, you will be.

Tax and obligations – for orientation only

We don't advise. Konsumgöttinnen notes that the tax treatment of goods is unchecked. At iShopFor, mystery shoppers count as self-employed per its FAQ, and the privacy policy records your IBAN and tax ID. Whether you have to register or declare anything is for the tax office or a tax adviser.

Common mistakes

• Joining every "free test". Signing up is a contract. Read the small print and the order button.
• Polishing the review. Terms of participation require reviews based on your own experience. Embellishing burns your profile and is unfair advertising.
• Reselling test products. See above: prohibited. Selling your own purchased things is different; see the guide Selling used items.
• Handing over personal data carelessly. A pure goods test needs your address and profile, but neither bank details nor an ID copy. For paid assignments (studies, mystery shopping) the provider needs payment details for the transfer and sometimes an identity check; give them only through the provider's official, verified process, never by email or chat.
• Pinning hopes on a single draw. If you rely on a lottery you'll usually come away empty-handed. Spread your applications, but carefully.

Frequently asked questions

• Can I be a product tester as a side job? Not as a reliable source of income. As occasional goods or extra cash from studies and mystery shopping, yes, with fluctuating assignments.
• Do I have to give my address? For product shipping, yes. Check the operator and privacy notice first.
• Can men take part? At Konsumgöttinnen, per the terms of participation (as of April 2026), only women aged 18 or over. Studies, mystery shopping and app tests have other requirements, usually adulthood.
• What if an invoice arrives? React immediately, dispute that a contract exists, revoke as a precaution and contact a consumer advice centre.
