The website, colafridge.review, is a scam and is not associated with Coca-Cola or Mini-fridge. The website tricks potential victims into submitting their email addresses by claiming a testing campaign has just begun and Coca-Cola is offering them the opportunity to become a reviewer for the Cola mini-fridge. And, all they have to do is answer a short quiz, and you will receive their own mini-fridge. But, they will never receive the mini-fridge they were promised and the scammers may start sending them spam and malicious emails to the email addresses they have submitted to the fake website.
