I got a SoundBite last year and yes, it does work well, but the SoundBite company said they would do all the work to do what was necessary to get it covered since I had called my insurance company and was told that I do have prosthetic coverage. Unfortunately, SoundBite has not worked to get the insurance payments. First, I had to call them many times to get them to keep going to the next step of dealing with the insurance and now they tell me that my insurance won't pay because I didn't have the right kind of prosthetic coverage, but they are the ones who told me what to ask my insurance company.
They are very nice, but are more interested in selling the device than understanding what is necessary to get it covered. If I had the correct information beforehand to ask my insurance company I might have made a different decision.
Check very carefully with your insurance before signing any papers with Sonitus/SoundBite.
