I use them for a few months.
Excllent product, very nice presentation and finishing + quality.
Very good sound quality, good optical quality no bug in reading for now.
Fast, reactivates, and accuracy of all easy to use.
Rating 9/10 because the jog is actually less practical than the CDJ 800, sometimes my fingers "slide" on the jog and jog lack of "rolling".
Apart from this it is the cream ...
Oh yes! the price! Pioneer, it's a bit pricey even.
But ... the quality is paid.
