I really like Pioneer XDJ-RX and see users are quite happy with it's reliability. Before DDJ-SX I had XDJ-Aero but wasn't satisifed with it. It crashed several times when playing in small venues and at that time Rekordbox was not supporting Playlists, so it was not the product I could trust.

Since XDJ-RX is much, much better than little brother Aero, the XDJ-RX2 or XDJ-RZX will be my next buy, however I would wish it to be a little bit improved and I will probably wait for the next version. I hope it will be released at the beggining of 2017 and by the end of the tax year 2016 ;).

- DJM CUE style

- it should have BEAT FX like DJM900NXS2
