I guess if it's a good seller. But eBay refurbished usually just means they turned it on and wiped it down. It's not like Apple refurbished.
Mine was used. I have a single seller on eBay I stick with. As they've always been good for me on phones. They even list if the battery is 100%. Plus they take pictures of the actual phones from multiple angles. Rather than using a stock photo. The seller is thegizmotrader if you're interested. Make sure the names right. As there are sellers with similar names.
They don't offer a warranty though. Just the general eBay protection. Also for some reason they won't get a new camera. So, you'll see spots on every phone that are actually from the camera.
