I would refrain from purchasing a "renewed" camera, and would advise all others to do the same.
When it comes to "refurbished' items, I'll say to only look at an item refurbished by the manufacturer. But before you buy, look at your savings by buying refurbished over new. Some times it is a very small savings, and some times, it isn't a deal at all. For instance, right now, at this very instant, you can purchase a brand new Nikon D850 from an authorised US dealer for about $2499. And right now, at this very instant, the price of a refurbished Nikon D850 on NikonUSA.com is about $2799. Why pay $300 more for a refurbished camera over a new one? The dealer with the new product for $2499 is selling refurbished models for $2399. To me, this is not enough savings to make the case for purchasing the refurbished model over the new one.
My experience with purchasing Nikon refurbished products isn't as good as others' on this site. I will refrain from the refurbished market in the future.
