Seemed like a good product but...
First I will say that I use a memory foam mattress.  Because of that I usually sleep on the same side of my body, in roughly the same position all night.  I tried the sleep mask several times and while it did help me to fall asleep, when I awoke it had slipped from over my eyes up onto my forehead.  I tried fastening the velcro tighter, but that didn't help.  This is my first sleep mask, so I do not know if this a common problem or not.
