I've read all kinds of reviews on the internet about the mixer being unstable.... If handled with care and not taking out cables with phantom power on, there should be no issue. The internal wireless of the unit might be the weakest link, however, if you keep it on stage, you should have little to no problems with it. The features this mixer has is a steal for the money. You get DBX Feedback suppressor, eq on mains, channel strip on every channel. The Matrix is programmable. You can record on a usb stick, you can do whatever you want basically. Some think of it as a "toy" mixer, but that is because they never used it. The preamps sound great as well. It gets the job done. You will never feel that you overpaid for it and you will be satisfied if you know how to use a digital mixer.
