good enough [SEP] it keeps light out as it is supposed to do but the strap really cuts into the top of the ear and it is 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 have tried putting tape over it but it falls off because i toss and turn a lotaside from all that discomfort stuff it works and it is good enough for now
