Too tight
I’ve had the opportunity to test quite a few face masks.  This one would be near the bottom of my list.  Let’s start with the good.  It is very lightweight.  It has a nice formed foam and doesn’t rub on my eyelashes.  It comes with a cooling gel pad.  There are several issues as far as I see it.  First and most important, it doesn’t fit well.  I have it set to the very end of the Velcro and it is still tight on my head.  I do not particularly have a large head.  As a matter of fact, I can wear some youth baseball caps set on the largest setting.  This elastic tugs far too much to be comfortable.  The next issue is that this thing has a cord that isn’t much longer than 3.5 feet.  That means you have to be close to your power source.  You can use a usb battery but they are expensive if you don’t already have one.  With regard to the heat, this mask on the hottest setting just got lightly warm.  Most of the heat seemed to be in the raised areas where the eyes go and not the part that touches your skin.  It means that it has to heat up the air between you and the eye area in order for you to feel the warmth.  It’s just not warm enough for me.  Since the cord has to be attached to the mask via magnet, with such a a short cord, basically I have to sit perfectly still.  No way I could actually wear this to sleep in unless I found a way to mount the usb battery near my head.
