Title: NOT THAT GREAT
Review: I bought two of these and installed them on different phones in different locations. They do magnify the sound but also give a ringing feedback when you pick up the phone which the caller also hears. If you turn down the volume.. guess what... no amplification!I took them off. Not worth the inconvenience, in my estimation.
