Hi friends, it a very useful and effecting product. easy to use just have to hang it . it refreshes the bad or unpleasant smell into sweet smell so that we don’t have any issues with bad smells. as it was hard for me to even breath in my own house due to smell coming for neighbor house, I was very unhappy that I cannot take breath in my own house . then I hear about this product ODONIL and when I used it, it changes every thing, it changes the whole environment of house and now whenever I came back from my office I like to take deep breath just feel the aroma of the house. it all happens because of odonil.love this product
