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.
