My first aids were RIC, then BTE, now RIC. I am NOT happy with the longevity of the Resound rechargeable RICs. They have lithium ion batteries built-in; the entire aid must be replaced when the batteries no longer hold a charge, as in 3-5 years. Forced obsolescence.
I also find the receivers last less than one year. In BTEs, you have to replace the tubes. In RICs, receiver replacement are much more expensive out-of-warranty. I no longer care about cosmetics in hearing aids. And yes, the teeny-tiny RIC wax guards are a pain.
