GREAT Concept -- but adhesive fails easily
I love the idea behind these masks and found them quite comfortable. Unfortunately, I've found that if you sweat at all in the area where the adhesive touches the skin – even a minuscule amount on otherwise clean/non-lotioned skin – the adhesive will detach and leaks occur. It is pretty hot where I live, so it's nearly impossible to avoid the occasional tiny amount of face-sweating. It would be great to have a version with a stronger adhesive for such climates... I will probably save the remaining masks for wintertime and hope I can use them then.
