Query: Junk

Bought this to replace a $10 battery operated transmitter I bought 8 years ago. The older transmitter works well to about 25 feet. I just wanted to be able to use an AC adapter instead. Followed the included instructions. Range was about six inches. Volume wheel seemed to be rubbing against the edge of the casing. When I touched the wheel, I got horrible static. Oh well, back to the factory and back to using batteries.
