horrible eye mask [SEP] i hate this eye mask so much and the super annoying constant emails from dr jenna zigler the creature of the product the strap was so uncomfortable i cut it off seconds in the microwave would do nothing i heat mine for seconds and it still doesn t stay hot for more than minutes mine has never burned i don t know what people are talking about it s too hot to put directly on my eyes but if i only microwave it for seconds it s useless i put in the blue sack until it cools down then i can use it for about minutes minutes yeah right also the opposite side gets all fuzzy just look at my pictures it is definitely not worth you d be better off boiling hot water and using a face towel to put over your eyes or using an activated disposable hand warmer like hot hands that stays hot for hours expensive and not reusable but they work
