I bought mine straight from Dyson but also refurbished. There’s some little scratches on it, but I’d rather have that than pay full price. It’s absolutely worth it IMO.

Hello, thank you for sharing your concern with us. Dyson Refurbished machines refer to as certified machines that have been previously sold by Dyson and were returned. Once returned, each machine is hygienically deep cleaned, tested, and inspected to meet the Dyson quality standards. Genuine Dyson parts are used where replacements are needed. All refurbished machines are covered under Dyson warranty- you can check the Dyson official website for complete information on the warranty. https://www.dyson.com/inside-dyson/terms/the-dyson-warranty,here is the website link for your reference.

The “is this fake” posts are from people buying it second hand (used) from like Facebook marketplace or the like. Best Buy is fine.
