Product review (5 stars): Worked Great
My wife likes to use a shoulder rest when using our cordless phone.  One of our Panasonic phones from many years ago had one and she got spoiled.  I have done a lot of Internet searching and have not found a replacement.  This shoulder rest attachment works on most of the newer Panasonic phones by clipping to the belt clip.  Until I found this, I have been using JB weld and other glues to put the original back together when she would drop the phone and break this attachment.
