Title: Disapointing Results
Review: I Bought this Telephone Amplifier as an aid to hearing conversation better.The sound level on my end was fine but not clear .The tone control was about useless. People on the other end of the phone could barely hear me. It was certainly a disappointing unit.I Had to return it.Thanks Amazon for your excellent return service.
