Thank you for viewing this product m(__)m This is the I-O DATA DVD Super Multi Drive DVRP-U8NKA! Overall, there are fine scratches and signs of use. Also, there is a large scratch on the top panel. I connected it to a desktop PC and confirmed that it works without any problems, but it did not work with a tablet PC and mini PC due to insufficient bus power. If you are considering using it in such an environment, please purchase an AC adapter separately. This is not covered by the warranty. I have performed a simple operation check, but if there is a fatal initial defect such as it does not start, I will accept returns within 3 days of arrival. Please check the operation as soon as it arrives (I have taken a picture of the serial number to prevent swapping). Please check the photos carefully for the condition of the product and purchase it after you are satisfied. We cannot accept claims or returns for areas that can be confirmed in the photos, so please be aware of this. *If you wish to purchase multiple items, we will discount the shipping cost, so please let us know in the comments. 075
