    What is your opinion of this product?
    I picked up this set for my gigs and it works, I am still learning what channels work best. What makes this a learning part is that there is a lot of radio signals where I live that could interfere and sometimes these don't happen till after you've done your sound check. But once I figure out what channel works best here, I will be happy. They work for what I need.
