Hopes dashed!  Not for us!
This product did not work for either myself or my wife.  The promise was that they would fit comfortably.  That was not true for us.  My wife lasted about thirty seconds!  I persevered for thirty minutes trying every combination of adjustments I could think of with no positive result.  There are three problems that I see.  One: the first is the heat factor.  I was literally dripping sweat by the time I took mine off.  This is in a 70 degree room with a ceiling fan and a personal fan in my face.  Two: The seam that joins the two pieces meet right in the middle of your chin - which is the center of the pressure to pull your chin up!  Not good!  Three:  The straps did not pull my mouth &#34;up.&#34;  The pulled my bottom jaw &#34;back&#34; and literally opened my mouth.  Entirely the wrong result!  Furthermore my jaw was aching by the time I gave up.  Please note that my thirty minute trial was with me really wanting this to work.  The whole family is coming to the point of my snoring being a family joke.  I really wanted this to solve the problem.  Not!
