This product is not so useful as I have seen any major difference. The product is easy to use but its not useful. Its a total wastage of money. Although it is long lasting but what the use if it doesn’t work. I am using this product for 3 months but I have not seen any good result. Still I have been bitten by mosquitoes.
Though, these products are launched in marked with some certifications and approval of governing body, but any chemical formula, would have it’s side effects, while used for long run. I would strongly recommend other not to buy this product.
