I went 2 years ago, I postponed it for both the recommended treatment method and economic reasons, but then I was invited to meet by calling IDIS telophone I was desperate, but the tests and the behavior of me and the other customers I watched were extremely polite and respectful, especially the information about the devices after the tests was extremely enlightening. I even said, "After this lecture, I don't need to read the prespectus of the devices," I said, if you have hearing loss, IDIS is with you on everything. Thank you, IDIS . Respects
