comfortable, heats well
This mask is pretty comfortable.  The velcro band makes customizing fit perfect.  It blocked all of the light.  It provided a good amount of heat to the eyes, in the three different heat settings.  Low feels pretty good, just a light heat.  High power and it was all over really warm.  The power port has a very strong magnet which seemed to stay in place, even with moving around.  It also has timed settings from 15, 30, 60, 90, and  00 that  automatically shuts it off.  This also came with a blue gel insert that you can get cold for a cooling the eyes.  It also came with a set of foam earplugs in their own little case.
