This product achieved no results.Only fell off during sleep.
Sleep apnea is very serious and this product is a farce at best. Went to great troubles to get a refund following necessary procedures. The checks in the mail game was played for a couple months. Check does actually come only to be dated 28 years into the future.
Then noticed writen amount did not match the number amount.
Do not waste your time or money with this product or the false claims that this product can work for you.I have since tried other routes to help my mild apnea problem with good results.
