Quick to work, efficient workflow and great sounding.
The small formfactor also helps out a lot when out on smaller gigs where a full scale mixer is required but there is no room.
Used it quite alot in smaller clubs and for FOH use at larger (when there is a monitor tech).
+ for build quality
+ quick
+ easy to learn
+ small
+ connectivity (dLive, other SQ, Qu, and with the dante-card anything.)
- not fully developed when i bought it. (now updated and great!)
All in a all a great mixer.
