My elderly mother is in need of a hearing aid but due to her suffering from dementia, I am afraid she will be constantly loosing them. Does anyone have any experience with the disposable aids? Would you recommend them?

I am not familiar with the disposable ones but one not get her a good hearing aid with a cord attached to it that has a clip on the other end to clip it to her shirt/dress collar? This works well because even if they take the hearing aid out of their ear it stays attached to the clothing.
