I think that you are correct about them saving money in the long run by selling me the Expresslink - so far I have not asked them to make any adjustments to my OPN 1 hearing aids and have done it all myself so they haven’t had to spend any time or ship me anything to accomplish it.
There is a bit of a learning curve to using the Genie 2 software, however. I think I have figured out most of it but since I have no training as an audiologist I’m sure that there are some things that I am missing when it comes to programming my aids. On the other hand, I am very happy with the OPNs so the programming seems to be doing the trick for me.
