Query: Simple to use but poor signal.

The Rocket FM transmitter was as easy as a mouse to set up and get running. The tuning app is about as easy as software gets to use.However, no combination of orientation of the transmitter and receiver and frequency I tried managed to get a range of more than about 4 feet, usually a LOT less.I see now why it was in the ultra discount bin at the record store. I will be returning it and would not pay $5 for it.
