Does not last, I wash my boat religiously every time I get home and the plating on this light just is awful. Noise cancellation??? Not sure if I noticed any difference between this piece and one without this feature. Most of the time they will not fall out. My major complaint is how much dirt and debris these pick up! You should be able to engage the pad over the top and bottom bumps. when opened, it looked same, but oh my god, the buckles are fixed with tiny little wire kind of things look like staples, dont know how long it will stay there. 5 would be better but they seem to be in short supply. Looks like dollar store packaging, with god-awful flame artwork printed on a home color laser printer. Forgiving size wise and the underneath is stretchy. I?ve worn them with thin socks, thick socks, and barefoot.
