What is your overall opinion of this product?
Very good, solid construction. Note that the 7 band graphic works for EITHER the mains or monitor, not both. The only monitor output is a 1/4"TRS, you'll need an adapter to go to XLR. Lots of input options. The built-in FX are limited to some presets, best to stick with simple reverb for live applications. Like all mixers with USB, the USB output can be noisy (16 bit, too), but unlike some USB mixers, there is a volume control on it, so you can turn it down to avoid the digital converter noise. ALthough they call it a 12-channel mixer, it really has 6 mic preamp channels, 2 stereo input channels with full EQ, and an aux stereo input with just a volume control - this is no different than other mfr's offerings.
