This is a very good mixing desk for the price. Some say Behringer is "low quality" but I find this desk very good value for money. Of course it could have more features but then you'd need to pay more for that. To be more precise, one first must think very well what uses one will give to the a mixing desk before deciding, as each has its own specifications and potentialities.
I bought it mostly for the possibility of attaching effects units or monitors, per track, PRE-Fader. Thus is useful to connect my Kaoss Pad 3 because I can feed the whole signal to the KP3 and turn the volume all the way down on the track on the desk and then I manipulate it completely on the KP3 (pure wet signal). This is not possible with Post-Fader sends.
All the rest is perfectly acceptable and works fine. For me, a very functional mixing desk. Also a few alternative ways to send signals in and out (headphones stereo out, RCA in/out, main stereo out, USB stereo in/out) so I can connect to monitors, the computer via USB, etc. all at the same time.
