As a parent with hearing impaired kids, I can’t stress enough how bad of an idea this product is. If you think you need this device you should get properly tested and if needed, fitted with a properly programmed hearing aid.
I agree with this statement. You couldn’t be more on the spot. Waste of money and this could be damaging to your hearing healthcare. Seek out a professional.
So not a good idea for the mother in law who loses hers all the time as a cheap back up so she stops yelling at us during the holidays?
