The instructions you provided by email were more informative than the ones that came with the device. I am now able to remove it without pain. I still can't sleep with it in my mouth, so I don't know if it controls my snoring. I am disappointed that you will not refund my purchase price, since I am unhappy with your product. You could count the one I used as one of the free ones, and return the price of the original one. For this reason, I will not recommend it.
