Using these as part of a school sound system, with the 3 other microphones in the range.
They are great little microphones, fantastic range, the receiver has a handy light which shows you when the microphone was on, battery life in the unit is very good.
The only downside to this unit is there is no XLR output on the receiver, although for the price i wouldn't mind giving this up.
Great value for money, highly recommended!
