ergo(?) hearing aid. Hello this is Denise calling from jericho(?) Hearing Aid. Someone had inquired about our device. I just wanted to ask you if you wanted to try something or or you just looking for information and we do ask you questions about your hearing to see if you would be a good candidate before we send them out to you. It is a 45 day money back trial period if you are interested in trying then also I sent you an email with my information. Give me a call back when you are available. My phone number is 615-455-2207. Thank you and have a good day bye bye.
