I had been using a cheaper wireless for years and had problems with signal dropout and power. The moment I powered this unit up and tested it, I was amazed! The strength of signal was like a steroid shot! and the 470-534 MHz bandwith meant that I never had to worry about competing devices or cellphone interference! Playing different venues every weekend, like I do no longer presents the old headaches. If you're on the fence about spending the money, rest your mind! This is the mic you've been looking for!
