To get a repair or cleaning from Costco in the Chicago western suburbs is less than a week. I have a KS9 and I suspect either my receiver or receiver wire is starting to act up. It quit, threw it in the dehumidifier, waited a couple more days and it worked, but a couple hours later, the static came back. Inhave an appointment to have it looked at on Saturday.
I set up another appointment to get a hearing test and see if there is another new back-up to my primary hearing aid that I like. That appointment was det three eeeks out. So to get a heariing test and try out their hearing aid is 2-3 weeks.
