I used to have ear infections three times a year till doc recommended these (I have unusually small ear canals - probably could have benefited from tubes as a kid but anyhow).  Haven’t had an ear infection since and this was almost ten years ago!!!  Only had to have my ears irrigated once since that time, too, and it was when my most recent ototek ear loop had broken and I was between getting another one.  If that isn’t proof, I don’t know what is!  Told my uncle about them too, he of the chronic ear infections, and they helped him as well.  Get it!
