I recently purchased Odonil, I think 3 days ago, I was put then in my bathroom, I noticed that 1 days it may smell very much but next day their smell were goes down and Today its same low smell, my compliment is that their smell were fastely gone. I also appeal to Odonil make their coil much hard by which their smell not go fastely and the package of product makes its soo attractive and dashing. it is nice product and its flavour is also nice but it may be suggest them to make their coil more effective.
