Hi @OGN99  no way to know unless you go to Fitbit.com or to an authorized retailer (click for list)  Only the devices from Fitbit directly or an authorized retailer have a warranty. eBay isn't always the best since people will sell devices that have been laying about with dead batteries. Many people come here wanting to know what to do when they purchase a Fitbit and it simply doesn't work. To protect yourself, be sure whoever you get it from allows for returns. Facebook Marketplace is where many scammers can be found and doing a search for Fitbit can also lead to sellers who aren't legit. Always go to trusted sellers. Fitbit.com or that list of sellers I linked above.
