I just got my RZX and am about to return it tomorrow. The unit froze on me once in the first hour and the software crashed 3 times in the first hour. It also crashed more then 4 times while analyzing my tracks in export mode. Which never has happen to me till I upgrade to Rekordbox DJ performance software. I was ready to jump ship on serato but rekordbox made me realize how stable and resourceful it is. Serato has only crashed on me 4 times my whole life. I should have run the free trial first before I bought equipment to see how my laptop would take it. So I advice you to do free trial with video software and mix for a couple hour at HOME and if it dont crash on you then your off to a good start.
