Had a couple of these in at work on friday, think they are there on permanent loan.
Had one DJ use it, quite franly its a pretty trick bit of gear. Everyone in the booth was more interested in this than the 6 CDJ-2000s.
The nextbeat can be removed from the dock and taken around, so fantastic for a live performance and interaction with the crowd.
