It's despicable that folk should exploit individuals who are suffering and would do pretty much anything to get rid of their tinnitus. But, as they say, 'If something looks too good to be true, it probably is'.
Given that tinnitus is the final common pathway for so many pathologies, acoustic trauma, infection, wax etc., it is VERY unlikely that there will be a single entity to 'cure all'. Maybe that's the key. I have personally stopped looking for a cure. Some tinnitus just goes away, some gets quieter/louder with time,and most form are open to modification by treatment. Once tinnitus is accepted as a part of life, the impact that it has on life lessens.
I'm sorry that tinnitus sufferers are being exploited....those who are perpetrators are mean money grabbers. However, try not to gullible. If there were a 'Miracle Cure' it would be headline news given the number of famous folk who suffer, not some seedy website assuring us of universal success.
