I use ambi pur both at my shop and godown and the good smell gives a good impression to the customers. I used other room freshners before but they were not strong enough to counter the smell in my godown. Then I bought ambi pur which was strong enough to counter the foul smell in the godown. The smell usually lasts for a month and my favourites are lavender and sandalwood fragrances. These fragrances were not found in any other brand. Now I always prefer ambi pur and would also recommend it everyone.
