Being a DJ, this works great as an addition to my setup! Packed with extras like handhelds,lapels and headset mics you can go cable free with this product! Picks up nicely from about 100 feet as long as there's no blockage between the mic and the transmitter. Make sure the antennas are used and are both fully extended prior to operation to allow for maximum distance. Great buy and price and I'm glad I purchased these from Best Buy. The only downside is the width of the unit, it takes up alot of table space and the cable that's provided isn't nearly long enough(2-4 ft) for professional users. I had an extra cable that was 6 ft so this saved me another purchase. They shipped boxed and all the accessories were in there. I recommend buyer test and get familiar with functions, keep backup 9 volts batteries for handhelds before use and store in a cushioned bag to protect it if possible.
