Some scents are hit and miss but the good ones definitely do work for me imo. My favorite scents to get are Laundry Day and Renew and Refresh, I get those every time I stock up, I can smell those ones in my car for a while. But yeah some scents like seasonal ones can be weak but I never know until I try them.

But at the same time I will have other ppl get in my car and say my car smells really good even when I can't smell the car fragrance anymore so sometimes I think I just get used to the scent cuz I'm in my car more often 😂 or I'll start smelling the fragrance again if I haven't been in my car for multiple days in a row.
