good just not ideal for stomach sleepers
these are well made, do the job fairly well, but as someone who sleeps on there side and stomach i found them getting pushed around by my pillow if my face was facing sideways.  there was also a slight gap between the mask and my nose which let some (but not much) light in.  for people sleeping on their stomach i would suggest a mask which doesn't have &#34;shells&#34; for your eyes.  the mask will touch your eyelids while on but the upside is you can sleep with your face facing sideways without your pillow moving the mask<br /><br />update: Great customer service ! I was contacted by the seller who noted the mask comes with a 24 month warranty and offered to process a refund for me if i was not satisfied.
