Months after buying my pair of Signia aids, I have decided that they are indeed real. I think that they are from Canada, or possibly even Europe.
That would be a reason that they do not show up in the US data base. Like yourself I am a self programmer.
I purchased a new in sealed box Connexxlink. It paired right up with my new aids. It all works great! At a huge savings too.
This has all been quite an adventure and learning experience. Would I do it again? For a savings of many thousands of dollars the answer is a resounding yes.
I could never have afforded hearing aids if the only choice was the conventional route of acquiring them.
Thanks to everyone on this site for your input on this subject.
