If you're someone who likes experimenting with new stuff and expressing your thoughts, product testing could serve as a decent side gig. It lets you earn a bit of additional money or gift cards, and you can also retain the items you test. However, keep in mind that product testing doesn't provide a stable or predictable income, and not every opportunity may be a fit for you. Moreover, be cautious of scams or counterfeit deals that request upfront payment or your personal details.
