Review title: Didn't Work For Me
Product review: There are a lot of 5-star reviews for this product, but it didn't work for me. My wife is very hard of hearing. We have one Clarity phone with bass boost, and she loves it. So, I thought I'd try this amplifier instead of buying another amplified phone system. This way we could use it at home and easily take it with us if we traveled anywhere. There was incredibly loud feedback when the phone was first answered. That could have been due to our DSL line, but with/without phone filter, it didn't work. Also, in order to use the "boost" function, the button has to be pushed and held down while listening and then released when talking. It eliminates background noise by shutting down the telephone microphone, so the hard of hearing person has to keep their thumb on the boost button--press, release, press, release--throughout the telephone conversation. Kudos to Amazon for their return policy.
