whats good about the productgives the eyes room to blinkkeeps out the darknice touch the ear plugs as wellWhat Kills the productI bought this product in the past maybe a year ago and as it was a year ago still isthat the elastic/velcro band is much too short to go around the head of an average persons headI had to add some eleastic and sew the additions on to make it fit properly ... I hope the MFG willmake the band at least one inch longer for Average persons heads other than that EXCELLENT product
