I’m wearing the now old Signature 5 behind the ear aids, the batteries last ab out 6 days with light use (less than 10 hours a day). I have been given quality no cost support over the 3+ years I’ve owned the aids. They cost much less than the $5,000 mentioned price. Mine came with something like a 90 day trial period (going from memory) and a 3 year full warranty… and as I recall and didn’t need, a 2 year one time free replacement on an aid lost or damaged. Great value if they work for you.
Hitching on here, I have developed a bit of a static/interference/ performance in one ear, not the aids. The problem developed when one aid failed out of warranty replacement $140 as I recall it. I wore it for a while, several months before complaining it may not be working, yes dumb me, just after the warrantee ran out. The new aid works well in both ears, and both aids display the same performance problem in the right hear. Any ideas: my brain still needs to adjust to a working aid in the right ear? I have some nerve damage or other problem that my aids can not compensate for. I may need to see a ear MD, but will give my brain more time to adjust.
If this thread is managed and I have violated the hitch hike rule, let me know and I’ll post this elsewhere… I figured my input on Costco may be helpful to the original poster.
