Review on Selectable Channel Wireless Hand Held Microphone by Percy Haulin

I was commissioned to install a basic sound system in a school gym on a tight budget. At first I thought I'd never find a decent wireless device for the budget I had, but the GTD nailed it. Yes, they're cheap and the build quality isn't up to the standards of professional brands, but if you're standing this on a shelf and not moving it, I don't feel you can beat them. They have all the features you would expect from devices that cost multiples of the price. Very intuitive to use if you are familiar with modern wireless communication. Good sound quality, LARGE transmission range and good battery life in phones. I also have to thank GTD for their customer service. My original device was defective (one of the receivers would not connect to the PDA). I emailed them and they had a replacement receiver the same day. Since then I have ordered some accessories directly from GTD and received very fast service.
