I just went to their web site. I promise if you send your money to me, I'll send it back to you, and you'll still have your money. I looked for a "package insert" on line, but there is none. My mother-in-law once sent in $70.00 so she can look younger after applying "a newly discovered magic skin cream"...discovered by a doctor, and gosh, it's in Parade magazine...she still looks 70+. If Ear Perfect was the "real deal" your would have already been treated by your doctor. The only accurate thing on that site is that tinnitus has multiple causes, and that is why one type of treatment will never stop or cure it. From what I have read, tinnitus is a ringing in your brain that started from a feedback system in your ears that malfunctioned. You really are listening to the noise in your brain, rather than in your ear. My right ear is not even connected to my brain any longer, but I still hear those pesky crickets, on the right side. There is real work being done on tinnitus, bot I don't think is one of them.
