Toxic Substances and Indiscreet Apps: Only 7 of 19 Sex Toys Are Safe to Use

According to Germany’s consumer-testing foundation Stiftung Warentest, many sex toys are not safe to use. The organization cited problematic substances and discreet apps that collect sensitive user data, explaining the findings on Tuesday (paywalled article). Of 19 sex toys priced between €12 and €209 tested, Stiftung Warentest recommended only seven.

The evaluation covered twelve vibrators and dildos, four masturbators, and three anal plugs from well-known brands — examining factors such as toxic substances, workmanship, and privacy. Although only established brands were included, the test revealed elevated safety risks, Stiftung Warentest said.

Data sent to ChatGPT

Three pricey app-controlled toys reportedly transmit intimate data to the manufacturers. “The apps are very indiscreet and transmit usage statistics as well as user and device IDs. An iOS app even sent data to ChatGPT,” said Warentest expert Anne Mandt. She advised using the toys without the accompanying app. It was also problematic that the privacy policy is often not available in German.

Three products reportedly contained health-harmful substances: two toys showed high levels of the hormonally active chemical nonylphenol, and the charging contact of a vibrator released more allergenic nickel than legally permitted. Nonylphenol can interfere with the human hormonal system, and nickel can trigger allergic skin reactions.

During the test, Stiftung Warentest did not examine which devices deliver the most powerful orgasms; the focus was solely on safety.

Overall, only one toy earned a rating of “very good.” It is the rabbit vibrator “Müller Young Hearts Purple Vibes,” priced at €29.99 (about $32).

Stiftung Warentest had already tested sex toys in 2019. Back then, many of the toys also proved to be deficient (TheColu.mn reported). (AFP)
