Summary: Upgraded from the 800mk2. Using the USB drive now is a freaking time saver. No more burning discs and hauling around cd cases. It's great. The only complaint is the 850's do not have the link function that the 900 or 200's do. Meaning, you need 2 usb sticks for mixing instead of linking 1.
Summary: Great value for money. The platters and basic functions feel the same as top end club cdjs. Perfect for home practice and prep for club gigs. The 850 also works very well with Rekordbox. All pre-set cue points and loops are instantly accessible.
Summary: I have owned these players since they were first released back in 2011 i think and i have to say they are okay but after sometime you will realize that they are not worth the money you put in, pioneer never fix the bugs, never put any firmware upgrades.
Summary: The CDJ 850 is an awesome player! I upgraded from a small $90 Numark controller and this is a lot to take in. One CDJ alone is bigger than my entire old set up. I use Virtual DJ and I was worried about compatability but you just plug in the USB cord, press "PC" and it's ready to go.
Summary: I would give this a 4.5 Stars only because I've used the CDJ 2000 and the jog wheel feels a little better (but not worth the price difference). It's perfect for DJ's using time coded CD's (i.e. Serato). If you are using DJ Software, you don't need 50% of the functions on this unit.
