Feature:
I must explain my rating here. This unit is absolutely awesome and has great features. My use with this was on Serato, and it comes pretty much already set up and ready to go. I give it a 5 on features because it dosen't scratch. You can imagine my disappointment on an item called Da Scratch, not having the ability to scratch. My colleague suggests that DA Scratch is short for Dosen't Actually Scratch.

Quality:
Item is really compact and well built. Multiple units magnetically link together on the sides and they've built a mixer that goes along with these units as well.

Value:
Worth every penny (if you get past that it can't scratch).

Desirability:
Again, a lower score due to the misleading name of the unit.

Sound:
This unit has no sound of its own. It is used to control tracks on your computer / hard drive.

Ease of Use:
Super easy to use. Install software, plug in, boot up, start rocking.

Support:
Didn't need support.

Overall:
As far as Dj control surfaces go, I cant see replacing this item any time soon. Very easy to use, great options and very portable. The small footprint is great for the traveling DJ since you never know how much room you'll have to set up.
