These tiny vent clips like most vent clips do not put off a lot of scent due to their size... If you want to fill your car with fragrance and you dont like the larger hanging freshies.... I recomment adding a sachet in the same scent you order your vent clips in! Just throw the sachet under your seat or hand from stearing column! Works GREAT~ Sachet bags are STRONG, because they are fragrance soaked beads that have never been baked! Will last a LONG time!
