If you do not have positive results, we will refund your money entirely anytime within the first 30 days. 

Tinnitus is caused by many different things. Our studies and others have found that 80 - 90% of participants have positive results. However, your type of tinnitus may not respond. 

If you find that you're not responding to the program, send back your device (using the prepaid label) before your 30 day trial is up and you'll receive a full refund.
