568ex Nikon Refurbished
These are items that have had something go wrong and they needed to be sent back to the factory to be repaired. They are in good working order and come with a 30 day warranty.
Considerable savings over purchasing new and great performance.
Some items may show wear and tear. When refurbished, they are repaired mechanically, not cosmetically.
Typically, there is no user manual, box or carrying pouch. Although, on occasion one or more of those things may be shipped with the item.
