After reading the other reviews I was skeptical about this product, but it had the features I wanted so I decided to try it anyways. I have not been disappointed. I have had this mixer for a little over two months and have used it at least once a week. I will list the pros and the cons to this product.Pros:1. USB sound card is a wonderful way to get music from a laptop, I call square dances and didn't like the audio from the built in sound card.2. The handle on the back protects the connection on the underside (no mic connections here, there is a mic aux, I'll explain that later).3. Beat Counter, Square dancing requires all music to be at around 128 BPM so the beat counter is a wonderful way to make sure everything is in line.4. Mic audio extends the base a bit, but if you have good studio quality mics this is a good thing. If not use the EQ to reduce it out. There is a mic aux output which can be really useful; this output is the microphones without the music, really handy for hearing impaired wireless device inputs. The mic return lines are for adding effects to your voice at line levels.5. Phono input, this is vital for square dance callers as many older callers only sing to records.6. Separate maximum output gain for each input. This allows for different input levels to be accepted but guest callers don't know this fact because these are set before the callers come up to call and will not overdrive your mixer.7. Mono/stereo switch on output, this is a small detail, but really handy if stereo separation causes confusion for dancers who are nearer to one speaker than the otherCONS:1. sliders could be a little harder to move, I will agree with one of the other reviewers these could be a bit tighter.2. Not able to completely run two separate audio outputs, independently, Ok this is a small detail, but I am used to mixers for radio stations, I miss my program and audition outputs.3. The input switches on the underside are not well labeled for the phono and line input, I plugged into the wrong one first and had a really bad audio quality, then I moved to the line input and all was fine.4. A third mic input would be real nice.Overall I would give this mixer a 4 1/2 stars.
