Zipspin PDE Tech D121-L ZipSpin DVD Duplicator Works But Not Fully TestedPurchase does not include power cable. I used one to test unit but it is not included in the sale. A replacement can be easily found and purchased online. Unit powers on and boots up properly. All buttons function. Able to access all menu options. Both drives open and close normally. Unable to test duplicating ability. Unit is exceptionally clean and free from any blemishes.
