Purchased several years ago and used for home practice, but has been stored in a box for about a year. I have checked the operation, but please understand that this is a check by an amateur. On one of the CDJs, the vinyl speed adjust jog stops midway and doesn't change, so it is not recommended for those who want to change the vinyl speed. The connected cables are also included. Sold as a set only. #CDj #Mixer #CDJ850 #DJM850
