It works, and is affordable,

I was suspicious of the price, but my only options were way over my client's budget. I took a chance and ... It does work, it isn't horrible, and for my client's once-a-month use it is acceptable. It is easy to set up, the auto-paring is nice, the noise floor is pretty bad. As long as you keep the gain at or near zero, keep the mics VERY close to your speakers, and use a noise gate on a digital mixer (such as a QU 16) you will be okay. You are getting a lot for a little, so something like noise trade-off should acceptable.
