I don't want to give even 1 star. I used it for about 1 month and it didn't work for me at all. My sinus infection got worse and both nostrils were seriously stuffed then I had terrible headache whenever I used it. It's too pricey and waste of money. Using saline solution is still better.
이거 사용할 때마다 비염 더 악화, 양쪽 코 다막혀서 심지어 심한 두통까지 생김... 별 한개도 아까움,,,별 다섯개는 대체 누가 준거야???
不要浪费钱!使用约1个月,每次使用后鼻塞更严重,甚至引起头痛,毫无改善。谁给5颗星?连1颗也不行!
