This is an excellent little mixer for mixing 3 stereo input sources to a single stereo output. The sound is great and perfect for what it does. I used it for mixing dry signals from my amp fx loop with the fx keeping them totally wet. The only negative thing I have to say is the labeling on one of the channels started to rub off....perhaps the silk screening of the paint didn't adhere well.
I have used this to submix some keyboards live on stage to keep the number of inputs down to FOH. It's good for what it is and the price, I think I probably wouldn't use it in the studio where top quality is the main priority, but for onstage the price and it's usefulness can't be denied. The headphone output is really useful for local monitoring too, and with it's own level control. The pan knobs can be a little fiddly if you are a large-fingered person (!) but once they are set they shouldn't get knocked or accidentally adjusted easily so hopefully no need to go back to them.
