These mic's work best in smaller setting - produce a great deal of feedback if you travel a good distance away from the receiver. However, the overall quality for the price is great!
These were used twice so far and for being the cheapest set of 8 they worked OK. Once for a 8 piece choir in a parade float and once at a small indoor show. The mics have very short range, so they must be positioned directly in front of mouth and they have a front and back. You need to experiment to get consistent combo of distance from mouth and loudness. Dont range check while in the box. The mic cords must be extended to link well as they are the antenna. Due to the reliability issues in the cold weather, we were saying "test" as much as singing. Indoor there was not the same dropped link issues. If you have "real" productions or critical applications, you might look at something of a more professional grade. If it is not critical, then these are OK.
