Hello friends.i am indirajith.now I write about my usage experience about vicks inhaler.its commonly used for blocked nose while situation of heavy cold.its is nit possible if yiu a have blocked nose .how you inhale this.its not possible .and if you have some minor problem of cold.you can use this for easy breath and clearing the normal nose block.but the heavy cold block cannot clear by this inhaler.its just your waste of money.you can also use some oils in steam for blocked nose.thats may help you but this not.in my suggestion if you want a inhaler for a minor blocks in nose.ut may helps you. Thank you for reading my review
