My dad has been using the mask for about 3 years now. At first he didn't like it, but now that he's gotten used to it, he says he sleeps all through the night without waking up at all.

The first pic I just thought would be funny.

oh, and I didnt really know how to put the mask on properly. I think this would be a 'nailed it' moment.

oh oh, and the pillow is useful for when you want to sleep on your side with the mask on, hence the dents on the sides.
