This is the UGREEN NASync DXP4800 Plus. I purchased it through GREENfunding (crowdfunding). It is a brand new, unopened item, never opened since it was shipped from the manufacturer in its original shipping box. As it is precision equipment, I have carefully stored it indoors with strict climate and humidity control since it arrived. ・Model: DXP4800 Plus ・P/N: 55216 ・Condition: New, Unopened (shipping box unopened) ※ Since it is unopened, I have not checked the operation or confirmed the serial number of the main unit. ※ Whether or not it is covered by warranty is at the manufacturer's discretion. [2 years from May 14, 2025] ※ I have removed the invoice because it contained personal information. ※ This product does not include an HDD or additional memory. Please purchase and prepare them separately. ※ To prevent swapping, returns and cancellations are not accepted after purchase. ※ For damage during shipping, please use the shipping company's compensation system. As it is precision equipment, I will ship it carefully via Rakuraku Mercari Delivery (Yamato Transport). Please feel free to comment if you have any questions. I will respond as quickly as possible.
