Feature:
A standard power cable would have been nice, instead of the included AC adaptor cable. Also, a peak light on the stereo channels would be useful, and wouldn't take up much space. On the positive side, the phantom power works perfectly, the gain on each mono channel is VERY powerful, which is good for quick volume fixes. Also the choices for where the tape signal goes to (ie main mix, control room, fx, etc) comes in very handy when you want to record just yourself w/out the tape track in the background.

Quality:
It's a very solid unit. If you leave it on for a while, it does heat up. The manual says this is usual, so I guess I can't complain about that. I do have one stereo channel however that doesn't turn off completely. I had my iPod running through it, and with the level turned all the way down but the mix turned up, you can still hear it playing. Haven't had this issue on any other channels, so I am fairly confident it's an isolated incident.

Value:
For a 12 channel mixer at this price that works this well, it is definitely worth the buy. If you're like I was, constantly walking to your amp(s) to change cables, invest the money to buy this. you'll be glad you did.

Desirability:
"Big things come in little packages"... It's rather small, but with the silver color how it is, you might even call it sexy. And if you're a keyboard player, being able to EQ it and send more than one to the same amp should be sex appeal enough...

Sound:
I'm running an iPod, computer, bass guitar, keyboard, and an acoustic guitar through the UB1202 all to a bass amp, shelf system, and guitar amp, (wired diff. through control outs, main outs, and FX send), They all sound perfect.

Ease of Use:
Since the level controls are knobs instead of faders, I can't give this a 10. If you're like me, and know how to run a mixer, how to troubleshoot, etc, you'll have no problem. But if you're a more visual person, with a basic understanding, all those knobs start looking the same after a while. Overall, all of the ins/outs are in logical locations, with room for your fingers, which is very good.

Support:
Haven't had to deal with support

Overall:
It does everything I want it to. There is some room for expansion, which is always good. For instance, soon I'll have my own personal stage monitor for my keyboard(s), which would plug into the FX send. For recording, you've still got both your main and control outs. For a personal mixer, it does exactly what you need it to do.

Feature:
As with most of Behringer's stuff you get max number of features at lowest possible dollar. A ton of features for this price range, you won't find anything with more at this price point.

Quality:
Behringer's stuff is almost always the cheapest with the most features, and the only question is whether it's built to last and of high quality. I'm not ready to make a generalization of the entire brand but this mixer has been totally fine despite my fears that it might crap out cause it was cheap. As far as the physical construction, it seems plenty solid, obviously nothing you would want to throw around but knobs feel solid, fader is reasonably solid, enclosure seems pretty solid, connectors are good.

Value:
Pretty amazing value as long as it continues to work!

Desirability:
Come on...mixers? How attractive can they be? I got it cause it was necessary, and it does it's job. But I suppose the little blue and red lights look nice. It's definitely not ugly, looks reasonably modern and nice.

Sound:
Seems nice and quiet. I'm sure there are big-time studio consoles that are quieter but from what I haven't been able to hear any hiss or hum at all getting introduced to the signal chain. EQ is fine, not the warmest sounding but quiet and effective.

Support:
don't know, haven't needed to try

Overall:
Awesome features for the price, no noticeable noise, no flakiness whatsoever so far. I've had it for roughly a year and a half.
