Highlight

What's in the box: Usually one or more physical consumer products from a brand running a study, such as a food, personal care or apparel item, sent with feedback surveys to complete.

Highlight is not a typical subscription box. Its website is built for consumer packaged goods brands that want to run in-home usage tests, and Highlight handles the recruiting, shipping, in-home use and analysis for them. Shoppers come in on the other side of that arrangement. Highlight recruits real people to try physical products at home and give feedback, so testers can receive items without paying for them. That is why it appears among free box clubs. Set your expectations to match. You do not choose what arrives, and boxes are not guaranteed to come regularly. Brands use the platform for competitive benchmarking, reformulation and decisions about flavor names, packaging and pricing. What you test depends on which studies are running and whether you match the kind of person a brand wants to hear from. In return for the products, expect to fill out surveys and give honest opinions, sometimes on a deadline. The public site speaks almost entirely to brands, so it does not explain how to sign up as a tester, who qualifies or how often products ship. If you like trying new food, personal care or apparel items before they launch and you do not mind some homework, it is worth a look. If you want a predictable monthly box of things you picked yourself, look elsewhere.
