Amazing dual channel wireless mic unit. I use this at weddings, bars, pretty much any of my gigs. The range on these is amazing for the price and I haven't had a single dropout or any feedback issues. Would buy again and I recommend it anytime someone is in the market for a new wireless mic. Easily competes with the higher end units for a fraction of the price.
