Mediocre- but good for small theatres

My medium sized theatre has trouble with getting a perfect connection with these, for the price, i would expect them to work flawlessly. In fact, we are planning on returning one or two of the six. One is terribly frustrating, the other is a nuisance. They were beaten by our old tascams which are 10+ years old.

I recently purchased the ATW-3131a wireless microphone for our church, and has proved to be worth the money! The set-up was simple and quick, even though this unit has so many features. Super-good range allowing our pastor to roam wherever he needs! If you are looking for high quality worry free operation this is the wireless system to buy!
