If they made a thorough advertisement that an uncertified device can make tinnitus worse, I wouldn't buy it from China. Even if it cost one dollar.
Absolutely correct - The only way to get this done right is to get it from a reputable ENT / Audiology Group that has your chart and data and has attended an InService lecture about precisely where and how to affix these electrodes, how long and what level of intensity per day should it be applied, what sound pitch is applicable to each client, etc.
Only a prize fool would purchase on the cheap a Chinese knockoff and try this on a do-it-yourself basis. My ENT Doctor warned me that any error in electrical stimulation that adversely affected the Trigeminal Nerve would result in pain that would dwarf even severe tinnitus (check this out on the Internet - it is even called "the suicide nerve.")
4 to 6 thousand? So it will be unaffordable for 90% of the population? Bad business strategy.
If this is ever released, a cost of $4000.00 - $6,000.00 is not unrealistic.
Recall that I signed on for that useless (and now defunct) Desyncra, which ran just over $6,000.00.
You are entirely correct about how such flagrant overcharging is self-defeating in that it so reduces the potential customer base.
I have no idea why this has long been the policy for hearing aids; the New York Times reported that only one sixth of those with hearing loss could afford hearing aids (but now with the new FDA approval for selling them over-the-counter without a prescription, watch how the price will be drastically reduced.)
Let's also remember that if the Shore Device is ever available, Medicare and the Health Insurance Carriers will probably not provide coverage for the typically given boilerplate reason (as with Desyncra) that this is "investigative and experimental".
