Query: Good but doesn't last forever

I just bought my second one of these masks. I can't sleep without one because of the plethora of light in my apt in mornings. I've used it every night and its definitely the best mask I've purchased. I love the contours for the eyes so its not pushed up against your eyelids. It also really blocks out the light, nothing can get in, when its still new.I bought my first one a year ago and about 4 months ago I noticed it really became to stretched out to stay on my head anymore and I noticed the shape of the mask began to flatten. I received my replacement yesterday and comparing them saw how stretched out it had become but hey for the price and for the amount I've used it. Definitely worth it.I don't have use for the carrying case and the earplugs are standard ones that I wouldn't use more than once or twice.
