Query: Ringstop - snakeoil

I now have suffered with a very mild form of tinnitus for 2 years. Its in the form of a very feint very high pitched almost of the scale whistle in my head, which is present 24/7. 3 months after it started I bought more than the reccommnded amount (4 bottles) and followed the instructions on taking them. There was ZERO reduction in the tinnitus, no effect on it was heard at any time. I can find no independant proof such things work and i believe the previous review thats says ringstop works is probably from someone associated with the manufacturers or a retailer of it. Do not waste your money on this or other snakeoil "remedies". You will have more chance of getting a tinnitus cure for your money by donating it to someone who is there to help you, not con you. Someone such as the American Tinnitus Association or the British Tinnitus Association. I'd give this item zero stars but the dropdown list does not give me that option!
