THANK YOU!!
Thank goodness for these. I have spent years fiddling with the old design strap, pulling it back down over and over while trying to go to sleep. Buying a new one didn't help. It was just positioned wrong and wasn't going to work. I was always trying to think of ways to rig it... I at least put velcro dots on it, since the velcro was absolute crap and gave out right away, even though I only undid the strap to wash it. This new kind goes right where I was always trying to make the old one go. It lies lower, and stays put, and actually holds the mask on my face, so I'm experiencing less air leakage. All of this, plus its cheaper by half.  I'm so happy.
