I have been using these at least twice a month since high-school (20+ years) after having multiple dramatic ear infections that rendered me temporally unable to hear due to clogging. I was just at the ENT doc last week and he confirmed that my ears 1) look and function great and 2) there is no damage, at all, from using these mini turkey baster like devices when they are used correctly. I highly recommend them, but your own experience may differ and you should probably check with an ENT doc just to be sure.
