My family using vicks inhaler for the long time. Its basically used when your nose is blocked.
Only one name come in everyone mind that is vicks inhaler.
Each member of my family use it and beneffited by it . The process is simple just open the cap and inhale it for few times . You will feel better nose opening and a relief.
I dont remember any other product except it for blocking nose.
It is simple to carry and best value for money. Have it with you always if you have such problems frequently specially in cold season
