Deliberately falsely advertised product
I ordered 'semi cured gel nail strips' that are supposed to harden under a UV or LED lamp. Well - they do not! They stay soft and are much thinner than in the product video, they aren't made of gel and don't even stick to the nail. They're just cheap stickers. The seller offered me a discount code and offered me to keep the product, how generous. After I made clear that won't work for me, they didn't respond anymore. I'm currently trying to get my money back via paypal claim, so that hopefully works out.
