This product is Refurbished What is a Refurbished product?
Refurbished. Remanufactured. Reconditioned. Essentially, all of these terms refer to the same thing. But what does refurbished really mean?

A refurbished product is one that is sent back to the manufacturer or supplier for a variety of reasons, refitted with different parts as necessary, and then tested and approved for resale by the manufacturer or supplier. Refurbished products typically carry a warranty.

Yes, it can mean a product that was returned because it didnít work properly and was redone to factory specifications. But it can also be a product with a cosmetic blemish -- like a small ding on the telephone -- that automatically means it cannot be sold in stores. Or it could be a telephone that was returned simply because it wasnít the correct model the consumer wanted, but the consumer had opened the box.

In any case, refurbished doesnít necessarily mean that youíre buying a used product at all. Many refurbished products have never even been sold or used. In some cases, they are inventory overstocks that were never made available for sale or never shipped out to frontline stores.

Most importantly, refurbished doesnít mean that youíre buying a product with a defect or something else wrong with it. Refurbished products go through the same testing and approval process that all brand new products go through.
