The term "official refurbished " refers to an "official refurbished product" that has been refurbished and restored by the original manufacturer or an official authorised refurbisher. These products are usually inspected and repaired to ensure that their performance and quality are up to standard. Compared with the new products, the official product price is lower, with a certain warranty service. The process of refurbishment may include parts replacement, cleaning and testing to ensure that the product is as close to brand new in function and appearance as possible.
