There are so many air fresheners on the market. It is hit or miss. Well, the Renuzit Long Last Adjustable Air Freshener is a hit with me. Twist to release the desired amount of scent; my favorites are raspberry and tropical. It sits on a shelf, table or counter. I actually set them on clothes closet shelves to keep the air from becoming stale. This product seems to last much longer than other air fresheners I have tried.
