Feature:
I like the fact that the set up will allow you to extend songs, but the quick return and vinvyl modes are nice. I like the fact you can adjust your tracks similar to a record while mixing. The display, info, and also mp3 capatibility are also nice.

Quality:
This unit is built well. I have them and the mixer in a coffin. I travel with them a lot and they always are up for the task. They have perfored with out fail for the few years I have owned them. I usually have the other two drives with me but have never needed them. Oh, GO DIGITAL less cables to play with.

Value:
price rance comperable

Sound:
Nice unit, Overall I love the vinyl mode. I do not do a lot of scratching but mixing in that made is nice. I have two of these, a DJM-800 mixer, two american audio cdi-500's, and two other older drives. I have to say the cdj's are nice. The only thing I would have liked was three to four que buttons like my old drives had.

Ease of Use:
Smooth operation, and unit set up make for very easy operation.

Support:
never needed

Overall:
I will have them for as long as they perform..... a long time.
