Review (3/5): Good Enough
It keeps light out as it's supposed to do, but the strap really cuts into the top of the ear and it's a little awkward to sleep with the strap above/pressed up against your ears. The velcro is really sharp, so when I loosen the velcro strap, the "barbs" of the velcro tear at my pillow, damaging the fabric. So I have to sleep with these with the mask on really tight to prevent the velcro-barbs from damaging the pillows. I've tried putting tape over it but it falls off because I toss-and-turn a lot.
Aside from all that discomfort stuff, it works and it's good enough for now.
