New Songbird disposable hearing aids for $ 59 each- Revolutionary technology or junk?

I just saw an an ad for these things and it looked amazingly impressive for $ 59.00 each. If regular hearing aids are “thousands of dollars” per the ad claims how can these people do it so inexpensively? I can’t believe that not needing to change batteries as often for the more expensive models makes such a difference in cost.

The Revolutionary SONGBIRD DIGITAL - Disposable Hearing Aid

You get what you pay for.

AKA–> They are crap, but there might be a few thousand people who buy 'em and don’t send them back, so there’s profit to be made.

I’d like to add at this point that I should have said “allegedly” just before the word “crap”, and I would like to say that me leaving the aformentioned word out was simply a typo, and that the men standing behind me holding baseball bats, plungers and sporting spam and bologna hats are simply buddies, and not brutal representatives of any hearing-aid type companies.
